edit-command-line

[Zvi Har'El]

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:

Best,
