New Revision: 75481

Modified:
   pyrepl/trunk/pyrepl/pyrepl/readline.py
Log:
don't propagate exceptions raised inside the completer.  This mimic the
behavior of cpython's readline, and it's very unpleasant to see your
interpreter crashing just because you hit <TAB> and there is an error in the
completer
