1 Introduction
GNU Moe is a powerful, 8-bit clean, console text editor for ISO-8859 and
ASCII character encodings. It has a modeless, user-friendly interface,
online help, multiple windows, unlimited undo/redo capability, unlimited
line length, global search/replace (on all buffers at once), block
operations, automatic indentation, word wrapping, file name completion,
directory browser, duplicate removal from prompt histories, delimiter
matching, text conversion from/to UTF-8, romanization, etc.
UTF-8 is a great tool for tasks like writing books of mathematics or
mixing Greek with Chinese in the same document, but for many other
everyday computing and communication tasks an 8-bit code like
ISO-8859-15 is much more practical, efficient and reliable. There is no
such thing as an "invalid" or "out of range" ISO-8859-15 character.
To have Moe used as your default editor you need to set the environment
variables 'EDITOR=moe' and/or 'VISUAL=moe' in your shell
initialization file ($HOME/.profile if you are using bash).
If your text console doesn't show all the ISO-8859-15 characters, try
the setfont command from the 'kbd' package.
Moe needs a screen size of at least 24 lines by 80 columns. Take this
into account if runing it from a terminal emulator.
2 Basic concepts
- Buffer
- The buffer is the basic editing unit; one buffer corresponds to one text
being edited. You can have several buffers, but at any time you are
editing only one, the "current buffer", though several buffers (or
several parts of the same buffer) can be visible when you are using
multiple windows.
- Buffer handle
- The buffer handle is the data structure underlying a (possibly hidden)
window. It contains the window and cursor positions in the buffer. There
is no limit on the number of buffer handles that can refer to the same
buffer.
- Current line
- The line with the cursor.
- File
- Files are named units of text which are stored by the operating system
for you to retrieve later by name. To keep any text permanently you must
put it in a file.
When Moe loads a file, it creates a buffer, copies the contents of the
file into the buffer, and then displays the buffer for you to edit. If
you alter the text, you can save the new text in the file. This makes
the changes permanent by copying the altered buffer contents back into
the file. Until you save, the changes exist only inside Moe, and the
loaded file remains unaltered.
To create a file, just load the file as if it already existed. This
creates an empty buffer in which you can insert the text you want to put
in the file. The file is actually created when you save this buffer.
- Window
- Moe divides the screen into one or more windows, each of which can
display the contents of one buffer. The only limit to the number of
windows is screen size.
3 Invoking Moe
The format for running Moe is:
moe [global_options] [ [+line[,column]] file_name [file_options] ]...
Where global_options are a mix of editor options and default
file_options. Use '-' as a file name to read from standard
input. Note that the short option names use the same letters that the
options menu inside Moe. Most long option names have a negative form
'--backup' '--no-backup'.
Each file name may be preceded by '+line[,column]' to
start the cursor at the specified line and, optionally, column.
line and column are applied to subsequent files until new
values are specified for them.
Moe supports the following editor options:
-h--help- Print an informative help message describing the options and exit.
-V--version- Print the version number of Moe on the standard output and exit.
-1--orphan- Put extra files in orphaned buffers instead of in new windows.
-b--backup- Create backup files (default).
-B--no-backup- Do not create backup files.
-e--exit-ask- Ask always for confirmation when closing or saving-and-closing a buffer.
-H--smart-home- Normally, when you press the home key, the cursor moves to the beginning
of the line, and if you press it again, it remains there. With this
option, if the cursor is at the beginning of the line and you press
home, the cursor moves to the first non-blank character.
-i--ignore-case- Search in Moe is case sensitive by default. With this option you can
make it case insensitive by default.
-k n--keep-lines=n- Number of lines to keep for PgUp/PgDn. -1 means half window.
-m n--max-windows=n- Maximum number of windows to show at once on the screen. 0 means as many
as they fit.
-n n--indent-step=n- Number of spaces to add or remove when indenting or unindenting a block.
-s--search-wrap- Make search wrap. If end of buffer is reached and no match is found,
continue the search from the beginning of the buffer.
-u--auto-unmark- Turn off highlighting after block copy or move.
-x--rectangle- Turn on rectangular block mode. Provide basic rectangular block
operations, like copy or move. This mode won't work properly if there
are <Tab> characters in or at the left of the block.
Moe also supports the following file options:
-a--auto-indent- When auto indent is enabled and you press enter, or the text wraps at
the end of a line, the cursor moves under the first non-blank character
of the previous line instead of at the beginning of the line.
-l column--lmargin=column- Set left margin to column. The first column is column 1.
-r column--rmargin=column- Set right margin to column.
-o--read-only- Make the buffer read only.
-O--overwrite- Disable insert mode. Make typed characters replace existing ones except
at end of line.
-w--word-wrap- Automatically passes the current word to the next line when you type
past the right margin.
Numbers given as arguments to command line options or editor commands
(line, column, offset, etc) may be expressed as decimal, hexadecimal or
octal values (using the same syntax as integer constants in C++).
Exit status: 0 for a normal exit, 1 for environmental problems (file not
found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
invalid input file, 3 for an internal consistency error (eg, bug) which
caused moe to panic.
4 The moerc file
moerc is the runtime configuration file for Moe. In it you may
define default editor options, default file options and file name
dependent options. The moerc file is optional; you do not need to
install it in order to run Moe.
The options specified in the command line override those specified in
the moerc file.
Inside the moerc file, file name dependent options override those
specified as default file options.
You may copy the system moerc file ${sysconfdir}/moerc
to $HOME/.moerc and customize these options as you like. The file
syntax is fairly obvious and there are further instructions in it.
5 The status line
The status line is a line displayed in inverse video at the top of each
window, and contains the following information:
- The keyboard status. Shows the already typed part of a multy-key
command.
- The status characters. 'I' for insert mode, 'O' for overwrite
mode, 'W' for word wrap, 'A' for auto indent, 'R' for
read-only, and 'X' for rectangular block mode.
- The name of the file being edited, or '(Unnamed)' if the buffer has
not yet been named. If the buffer has been modified since it was last
saved or opened, an asterisk '*' will be displayed before the name
and '(Modified)' will be displayed after the name.
- The cursor position in the buffer (Line Column).
- A 24-hour clock (with blinking dots).
- The help key (or the code of the character under the cursor).
6 Keyboard commands
Moe tries to rationalize the keyboard commands. The <Alt> key is
used for harmless commands like cursor movements and scrolling. The
<Control> key is used for more "dangerous" commands like copying
text blocks, deleting lines, or exiting. The <Tab> key is used for
file name completion and also shows/hides the directory browser when Moe
asks for a file name to save or load. In any case, the unlimited
undo/redo capability of Moe makes very difficult to accidentally cause
an irreparable damage to your files.
Moe uses the function keys, so that the most frequent commands can be
issued with only one finger. The function key <F1> shows the online
help, and <F10> allows you to change the options. Believe it or not,
this paragraph and some experience with text editors is all you need to
use Moe almost as well as an expert. Forget about 'learning curves';
there is nothing to learn.
The <Control> key is displayed in the online help as '^', while
the <Alt> key is displayed as '^['. In this manual
Control-a will be written as C-a and Alt-a as
A-a.
Some environments "swallow" the <Alt> key so that it never reaches
the application. If this happens, press the <Esc> key, then release
it and press the desired key.
6.1 Function keys
- <F1>
- C-h
- Show the online help. Press <Page_up> to see the previous help
screen or <Page_down> to see the next help screen. Press <F1>
or C-h again to return to the editor.
- <F2>
- Save the current buffer to a file, automatically creating any missing
parent directories. It will ask you to confirm the file name. You may
save the buffer with a different name, in which case the modified status
of the buffer being edited does not change. Moe makes a backup for a
file only the first time the file is saved from one buffer.
- <F3>
- Load (read) a file in a new buffer. Pressing <Tab> shows the
contents of the current directory, or completes the name if there is
only one possible name to show. If the file name starts with ~/,
the ~ will be expanded to specify your home directory (tilde
expansion).
- <F4>
- Toggle between showing only the current window or showing up to the
selected maximum number of windows.
- <F5>
- Select the previous window.
- <F6>
- Select the next window.
- <F7>
- Undo the last change made to the current buffer. You may keep undoing
changes until there are no more changes to undo. The buffer will be then
exactly as when it was loaded.
- <F8>
- Redo the last change undone on the current buffer. The undo history is
linear. That is, if you undo some changes and then make another change,
this last change replaces the changes undone, so you can't redo them.
- <F9>
- Copy the selected block at the cursor position. This is a convenient
alias for the command C-k c.
- <F10>
- Show the options menu. This menu allows you to change some editor-wide
and current-buffer options, like auto indent, margins, word wrap, ask
before exit, etc.
- <F11>
- Show the buffers menu, a list of all the buffers being edited. This menu
allows you to select a buffer and make it the current buffer. Some
buffers may appear more that once in the list if they have more than one
buffer handle. The names of modified buffers are preceded by an asterisk
'*'. The names of DOS buffers are preceded by a minus sign
'-'. The names of modified DOS buffers are preceded by a plus sign
'+'.
- <F12>
- Select the last buffer handle where you pressed <F12> and make its
buffer the current buffer. This allows you to switch between two
buffers, or between two places of the same buffer, by repeatedly
pressing <F12>.
6.2 Moving around
The simplest way to move the cursor to the place where you want to edit
is with the arrow keys. Moe also provides commands to move to certain
points in the buffer.
- A-u
- Move cursor to the beginning of the buffer.
- A-v
- Move cursor to the end of the buffer.
- A-l
- Prompt for a line number, and then move cursor to that line. Line 1 is
the first line. If the line number is preceded by a plus or minus sign,
it is considered relative to the current line.
- A-c
- Prompt for a column number, and then move cursor to that column. Column
1 is the first column. If the column number is preceded by a plus or
minus sign, it is considered relative to the current column.
- A-o
- Prompt for an offset value, and then move cursor to the byte with that
offset from the beginning of the buffer. The first byte in the buffer
has offset 0. If the offset value is preceded by a plus or minus sign,
it is considered relative to the current offset.
- A-b
- Move cursor to the begin of the selected block, if begin of block has
been set and is in the current buffer.
- A-k
- Move cursor to the end of the selected block, if end of block has been
set and is in the current buffer.
- A-f
- Move cursor to the matching '(', '[', '{', '<',
')', ']', '}', '>', '"', ''', '`',
'/*' or '*/'. Default movement is forward for undirected
delimiters. If the cursor is not on a valid delimiter, Moe tries to
guess what delimiter to match.
- A-g
- Like A-f, but default movement is backward for undirected delimiters.
- A-d
- Center cursor. Scroll window so that the line with the cursor is
vertically centred.
- A-w
- Scroll window backward (scroll up) leaving 'keep-lines' of context,
or half screen if 'keep-lines' is -1.
- A-z
- Scroll window forward (scroll down) leaving 'keep-lines' of
context, or half screen if 'keep-lines' is -1.
- A-a
- Scroll window left 8 columns.
- A-s
- Scroll window right 8 columns.
- C-k 0..9
- (Control-k followed by a digit from 0 to 9).
Set one of the 10 user bookmarks at the cursor position.
- A-0..9
- (Keep the <Alt> key pressed while typing a digit from 0 to 9).
Move the cursor to one of the 10 user bookmarks.
- C-k e
- Extend bookmarks. Set at lines 100..900 the user bookmarks 1..9 that
were not previously set or are repeated (point to the same character
that a previous bookmark).
6.3 Inserting text
To insert printing characters into the text you are editing, just type
them. This inserts the characters you type into the buffer at the cursor.
The <Backspace> key deletes the character preceding the cursor,
while the <Delete> key deletes the character at cursor. You can
delete a whole line with the C-y command.
The <Return> key inserts a newline character in the buffer. If the
cursor is in the middle of a line, <Return> splits the line.
Moe can split lines automatically when you type past the right margin
if you turn on word wrap in the options menu (see Function keys), or
from the command line when invoking Moe.
If you prefer to have text characters replace (overwrite) existing ones
rather than being inserted among them, you can activate overwrite mode
pressing the <Insert> key. Pressing again the <Insert> key
activates the normal insert mode.
To insert a control or special character in the buffer, use the command
C-p. It will prompt for a character code in a number of formats
and insert it at the cursor.
6.4 Searching and replacing text
The C-f command enters search mode. It will prompt for the text to
be searched for (the search string). The <F9> key will copy the
selected block in the string being entered. <F9> may be also used
when entering the replacement text.
The C-g command repeats the previous search or replace.
The C-w command searchs for the word at the cursor.
After entering the text to be searched, Moe will prompt for search
options. You may just hit <Return> to search forward with default
options or type one or more of the following options:
- i
- Ignore the case of the text being searched.
- n
- Do not ignore the case of the text being searched. Use it when default
is set to ignore case.
- r
- Replace text. It will prompt for replacement text.
- b
- Search backward instead of forward.
- g
- Search globally. Extends the search to all the buffers being edited.
- k
- Block search. Restricts the search to the selected block.
If you chose 'r' (replace) among the options above, every time the
search string is found, you will be prompted whether to replace it with
the replacement text. The possible answers are: y (yes) to replace
and continue searching, n (no) to not replace this text, but
continue searching, or r (rest) to replace all the remaining
occurrences of the search string without asking for confirmation.
6.5 Syntax of regular expressions
Regular expressions have a syntax in which a few characters are special
constructs and the rest are "ordinary". An ordinary character is a
simple regular expression which matches that same character and nothing
else. In Moe's regular expressions, all characters are ordinary
characters except '\', which is used to indicate a special
character or construct. Here is a list of those special constructs, also
known as "special search sequences".
- \\
- Matches a single '\'. See online help for more special characters.
- \?
- Matches any single character. For example, 'a\?b' will match an
'a' followed by any character and then a 'b'.
- \*
- Matches zero or more characters. For example, 'a\*b' will match an
'a' followed by any number of characters and then a 'b'.
- \c
- This works like '\*', but matches a C/C++ balanced expression. For
example, '\<for\>\s(\c)' will match any 'for' loop, even if it
includes nested parentheses.
- \+
- Matches zero or more instances of the character inmediately following
the '+'. For example, '\+b' will match any number of 'b's
(including no 'b's). '\+' may precede '\[..]', '\w'
or '\W', matching any number of characters from those in set
(including the empty string). '\+' may precede itself any number of
times, matching N-1 or more instances of the character inmediately
following the last '+'. For example, '\+\+\+b' will match two
or more 'b's.
- \[..]
- Character set. This matches any single character between the brackets.
Ranges of characters may be specified by writing the starting and ending
characters with a '-' between them. Thus, '\[A-Z]' matches any
ASCII uppercase letter. '-' may be specified by placing it first or
last. ']' may be specified by placing it first. If the first
character after the left bracket is '^', it indicates a
"complemented set", which matches any character except the ones between
the brackets. Character sets may contain escape sequences.
- \s
- Matches zero or more whitespace characters. For example, 'a\sb'
will match an 'a' followed by any number of whitespace characters
(or none) and then a 'b'.
- \S
- Matches the longest possible non-empty sequence of whitespace
characters. For example, 'a\Sb' will match an 'a' followed by
any positive number of whitespace characters and then a 'b'.
- \w
- Matches any word-constituent character (letters, digits and the
underscore) of the ISO-8859-15 or ISO-8859-1 character encodings. Other
ISO-8859 encodings are not supported by this command.
- \W
- Matches any character that is not a word-constituent.
- \^
- \$
- These match the beginning and end of a line. For example, '\^foo\$'
matches 'foo' on a line by itself.
- \<
- \>
- These match the beginning and end of a word. For example,
'\<foo\*\>' will match any whole word beginning with 'foo'.
And here are the special replace sequences.
- \&
- This is replaced with the text which matched the search string. For
example, '(\&)' will place parentheses around the matched text.
- \c
- This is replaced with the text which matched the search string
capitalized; the first letter of each word is uppercased and the rest
are lowercased.
- \l
- This is replaced with the text which matched the search string converted
to lowercase. For example, '(\l)' will convert to lowercase the
matched text and place parentheses around it.
- \u
- Same as \l, but converts the matched text to uppercase.
- \0 - \9
- (Backslash followed by a digit from 0 to 9). These are replaced with the
text which matched the Nth special search sequence, except beginning/end
of line/word, in the search string.
6.6 Block commands
Moe allows you to mark a region of text, the block, and then perform
some operations like deleting the block, moving it to another place (in
the same or another buffer), changing its encoding, etc. There can be
only one block at any given time. If you begin marking a block, any
existing block will be unmarked.
Here is a list of the block operations:
- C-<Space>
- Mark the beginning of block, or the end of block if the beginning is
already marked. If pressed in an existing block, unmarks it.
- C-k b
- Mark the beginning of block.
- C-k k
- Mark the end of block.
- C-k c
- Copy the block at the cursor. The text inside the original block remains
unchanged.
- C-k m
- Move the block at the cursor. The text inside the original block is
deleted.
- C-k y
- Delete the text in the block.
- C-k r
- Read a block of text from a file and insert it at the cursor. This
operation ignores rectangular block mode.
- C-k w
- Write the block to a file. The text inside the original block remains
unchanged.
- C-k i
- Indent block. Add spaces at the beginning of every line in the block.
- C-k u
- Unindent block. Remove spaces from the beginning of every line in the block.
- C-o 1
- Encode to Base64. Replace text in the block with its Base64-encoded
equivalent data.
- C-o 2
- Decode Base64. Replace Base64-encoded data in the block with its
corresponding plain text. In case of error, the cursor is moved to the
first byte of the invalid 4-byte group.
- C-o 3
- Encode/decode Rot-13. Replace text in the block with its corresponding
Rot-13-encoded text. Rot-13 encoding is reversible; running the command
a second time restores the original text.
- C-o 4
- Encode/decode Rot-47. Replace text in the block with its corresponding
Rot-47-encoded text. Rot-47 encoding is reversible; running the command
a second time restores the original text.
- C-o 5
- Encode to ASCII. Replace the ISO-8859-15 plain text in the block with an
approximate transliteration to ASCII-encoded text. Other ISO-8859
encodings are not supported by this command. Any ASCII text already
present in the block is left unmodified. This command does not simply
reset the most significant bit of each byte. For example, the control
codes '0x80'-'0x9F' are converted to the corresponding escape
sequences '0x1B 0x40'-'0x1B 0x5F', the 'latin small
letter sharp s (german)' is transliterated to 'ss', and the
'euro sign' is replaced with the string 'euro'.
- C-o 6
- Decode Quoted-Printable. Replace Quoted-Printable-encoded text in the
block with its corresponding plain text. In case of error, the cursor is
moved to the invalid character.
- C-o 7
- Encode to UTF-8. Replace the ISO-8859-15 plain text in the block with
its corresponding UTF-8-encoded text. Other ISO-8859 encodings are not
supported by this command. If the text in the block is already valid
UTF-8, encoding is not performed to avoid double UTF-8 encoding. If
'encode to UTF-8' is issued a second time and any character code
larger than 127 is found, the encoding is performed unconditionally.
- C-o 8
- Decode UTF-8. Replace UTF-8-encoded text in the block with its
corresponding ISO-8859-15 or ISO-8859-1 plain text. Other ISO-8859
encodings are not supported by this command. In case of error, decoding
is not performed and the cursor is moved to the first byte of the
invalid or out of range UTF-8 character. If 'decode UTF-8' is
issued a second time, the decoding is performed unconditionally, copying
any out of range UTF-8 characters unmodified and producing a document
with mixed encoding (see remove UTF-8 out of range).
This command also transliterates some non-Latin scripts into Latin
script (see Romanization).
- C-o d
- Remove all duplicate lines in the block searching forward and leaving
only the first of each set.
- C-o e
- Remove all duplicate lines in the block searching backward and leaving
only the last of each set.
- C-o o
- Remove UTF-8 out of range. Remove from the UTF-8-encoded text in the
block any valid UTF-8 character out of the range of characters managed
by Moe. In case of error, the cursor is moved to the first byte of the
invalid UTF-8 character found. This command can be used before
'decode UTF-8' to avoid mixed encoding in the decoded text.
- C-o l
- Convert all the letters in the block to lowercase.
- C-o u
- Convert all the letters in the block to uppercase.
6.7 Terminating your editing session
- C-c
- Close the current window without saving any changes. If the current
window is the only one for its buffer, and the buffer being edited has
been modified, or 'exit-ask' is enabled (see Invoking Moe), it
will ask you before closing the window.
- C-x
- Save the buffer being edited (if it has been modified), and then close
the current window. If the current window is the only one for its
buffer, and 'exit-ask' is enabled (see Invoking Moe), it will
ask you before saving the buffer or closing the window.
- C-q c
- Exit completely without saving. It will always ask you before closing
anything.
- C-q x
- Save and exit. Save all the modified buffers, and then exit completely.
It will always ask you before saving or closing anything.
6.8 Commands showing help and other information
- C-h
- Show the online help. See Function keys.
- A-i
- (Show character info). Show the line, position in line, position in
buffer (offset) and code of the character at the cursor. (The
'position in line' may differ from the column shown in the status
line because of <Tab> characters in the line).
- A-t
- (Show UTF-8 code). Show the UTF-8 code of the multibyte character at the
cursor. If the code is valid, the cursor is moved to the first byte of
the character.
- C-s 2
- C-s 4
- C-s 8
- (Show little-endian multibyte value). Show the little-endian value of a
sequence of 2, 4 or 8 bytes in decimal and hexadecimal. This is useful
for example to show things like the CRC or the file size coded in gzip
and lzip files.
- C-s <F2>
- C-s <F4>
- C-s <F8>
- (Show big-endian multibyte value). Show the big-endian value of a
sequence of 2, 4 or 8 bytes in decimal and hexadecimal.
- C-s c
- (Show character code). Show the code of the character at the cursor on
the status line. Repeat the command to revert to normal.
- C-s g
- (Show global status). Show the number of modified, unnamed and total
buffers being edited. Really it shows the number of buffer handles, so
the numbers may be greater than expected.
- C-s v
- Show Moe's version.
6.9 Commands for some special functions
- C-b
- Reformat paragraph. Break it up into lines that fit between the margins.
If the cursor is situated to the right of the left margin, this command
uses the cursor column as the left margin.
- C-p
- Insert a control or special character in the buffer. It also accepts an
arbitrarily large number in decimal ([1-9]...), hexadecimal (0x...) or
octal (0...), and inserts it as a little-endian sequence of binary
characters. If the number is followed by '+', a big-endian sequence
is inserted instead.
- C-y
- Delete the current line.
- C-o c
- Centre the current line between the margins.
- C-o n
- Change the name of the current buffer preserving undo history, user
bookmarks, etc.
- C-o r
- Redraw the screen.
- C-o s
- Split the current window into two. The resulting windows share the same
buffer. To undo the split just close one of the two windows with C-c.
- C-q <F2>
- Save to files all the named buffers that have been modified. A named
buffer is one with an associated file name. This function is very useful
if you do a global replace on many buffers at once and want to save all
the modified buffers without pressing <F2> a lot of times.
- C-q u
- Update copyright notices in all buffers, inserting the current year in
the list of years and joining the groups of 3 or more consecutive years
in ranges. For this to work, the copyright notice format should be
'Copyright <optional_text> <list_of_years> <copyright_holder_name>', and the year numbers must have four digits.
Year numbers separated by a comma ',' are counted individually.
Year numbers separated by a hyphen '-' are counted as a range.
7 Romanization
The first step towards mutual comprehension is a common language.
The first step towards a common language is a common alphabet.
Romanization is the process of transliterating a language from its
(non-Latin) script into the Latin script. It can be useful when the
capability of rendering the non-Latin script is not available. It can
also save space when using UTF-8. For example, writting a text with
Cyrillic characters needs twice the bytes than the same text written
with Latin characters.
The 'decode UTF-8' command (see decode UTF-8) performs a
context independent transliteration of Cyrillic, Greek, Armenian and
Georgian scripts, in UTF-8 format, into Latin script in ISO-8859-15
format. If the transliteration is needed in UTF-8 format, it can be then
encoded with the 'encode to UTF-8' command (see encode to UTF-8).
The 'decode UTF-8' command also removes unsupported diacritics
(carons, macrons, breves, cedillas, ogoneks, strokes, dots above and
inside) from Latin letters.
It can be hoped that in the foreseeable future every non-alphabetic
language will develop a method of romanization.
8 Other features
- Emergency save
- When Moe is interrupted by an abnormal event (a SIGTERM signal for
example), it will try to save all modified buffers in a file named
DEADMOE in the current directory.
- Basic 'less' emulation
- In read-only buffers the space bar moves forward leaving 1 line of
context, '/' acts as 'Find', and 'n' as 'Find next'.
- Binary files
- As Moe is 8-bit clean it is able to edit binary files, though in a
somewhat inconvenient way. If the file does not have any newline
character, all of it will be loaded as a single line.
- DOS files
- If Moe detects at load time that all the lines of a file are terminated
by a CR/LF pair, assumes it is a DOS file and removes all the CRs. The
CRs are restored later when saving the buffer to a file. If some, but
not all, of the lines are CR/LF terminated, no action is taken and CRs
are shown as control characters on the screen.

no one will ever know about them and they will remain unfixed for all
eternity, if not longer.
