Thanks, some notes:

I think the patch is a bit too elaborate and large. I would have
preferred to just catch the exception and raise ipapi.TryNext (i.e.
reverting to "behaviour as usual" if we are unable to be helpful
"easily") on failure. In the spirit of "worse is better" and "the
simplest thing that could possibly work".

Now if you could find the time to do that, it would be great! Some
kind of completerutil.py to which we could use to clean up
ipy_stock_completers.py (which is becoming a bit large).

BTW, I don't really like the way you don't replace \ with / in your
patch. Is there a problem with getting /'s, i.e. did you hit some bugs
because of them?
