python27 + readline: can't bind ^U

[Oliver Fromme]

Hi,

I'm using python27 on FreeBSD 8.1.  I would like to change
the behaviour of ^U at the Python prompt.  By default, it
deletes everything to the left of the cursor, but I want
it to delete the _whole_ line, regardless of the current
cursor position.

Nothing of the following works:

 - adding one of these lines to ~/.inputrc:
   "\C-u": kill-whole-line
   Control-u: kill-whole-line

 - adding "import readline" and one of these lines to
   ~/.pythonstartup:
   readline.parse_and_bind (r'"\C-u": kill-whole-line')
   readline.parse_and_bind (r'Control-u: kill-whole-line')

The desired binding is never executed.  When I run the
"dump-functions" command, kill-whole-line is listed as
unbound, and \C-u is still bound to unix-line-discard.

Other key bindings that I added to ~/.pythonstartup and
~/.inputrc work fine.  Only Control-U refuses to be bound
to anything else than unix-line-discard.

What am I doing wrong?

Best regards
   Oliver
