Wrong angle, I'm afraid.  There is no such thing.  You need to
store the PyObject (don't forget the PY_INCREF) and then pass
a pointer to a wrapper function in C to rl_bind_key().  The 
wrapper will call the Python function when it is itself called.

For a good example, go to

    http://newcenturycomputers.net/projects/readline.html

and download the source for my Alternative Readline.  I carefully
extracted (hacked and cut) some code from /F's windows console
module; it's called _rlsetup.c in the source distro for
Alternative Readline.  You could just look at /F's console
module source, but mine is a bit smaller and the _rlsetup.c
file is simplified.
