sorry you never got a reply.  This is strange, because the behavior
you describe is what you get when readline is *not* installed.  But
I've never seen the case where readline gets 'unloaded' by some other
module (esp. because the bulk of readline is in extension code, so
disabling it isn't obvious in python).  If you are still having this
problem, I'd suggest contacting the web.py authors, because they seem
to be doing something rather funky.
