Hi,
The function edit-command-line, which implements the ksh-like editing of the
command line using $EDITOR when v is hit, has a bug, which makes backslashes
escapes evaluated. You can try this by entering the command
echo 'a\nb'
and hitting escape and v. You enter your $EDITOR, and when you leave it the
command is changed to
echo 'a
b'
which is of course wrong.
The following patch, which adds a -R (raw) option to a print, solves the
problem:
