Wierd readline/inputrc problem.

[Jorge Santos <jsf@ciencias.unam.mx>]

I have a problem with programs that use libreadline, the thing is I
want to bind C-/ to undo, as in XEmacs, so I created the following
.inputrc in my home:

# This file controls the behaviour of line input editing for
# programs that use the GNU Readline library.  Existing
# programs include FTP, Bash, and GDB.
#
# You can re-read the inputrc file with C-x C-r.
# Lines beginning with '#' are comments.
#
# First, include any systemwide bindings and variable
# assignments from /etc/inputrc
# $include /etc/inputrc

#
# Set various bindings for emacs mode.

set editing-mode emacs

$if mode=emacs

Control-w: dump-functions
Control-/: undo
#"\C-/": undo

$endif



I want to use this binding on pgsql and zsh, well I think zsh doesn't
really use libreadline, and with pgsql when I type C-w (see above) I
get the following:

undo can be found on "\C-o", "\C-x\C-u", "\C-_".
                     ^^^^^^

The C-o binding didn't appear before creating my .inputrc, so it
appears to have been introduced by the "Control-/: undo" entry in
~/.inputrc.


What is going on here?!


Also, in bash the corresponding line is:

undo can be found on "\C-x\C-u", "\C-_".

so here, the binding is not seen at all.

Any help with this puzzling affair will be greatly appreciated.


TIA

P.S.

/etc/inputrc follows:

# /etc/inputrc - global inputrc for libreadline
# See readline(3readline) and `info rluserman' for more information.

# Be 8 bit clean.
set input-meta on
set output-meta on

# To allow the use of 8bit-characters like the german umlauts, comment out
# the line below. However this makes the meta key not work as a meta key,
# which is annoying to those which don't need to type in 8-bit characters.

# set convert-meta off
