Woah, til the python shell has tab completion! This does seem like undesirable behavior. I'd like to work on a fix for this if that's all right, assuming that this behavior should not occur.

I haven't exactly found where the tab autocomplete is implemented, but I'm assuming I'll find in one of the functions I see in the backtrace when I pause python at the interpreter prompt; maybe one of these? (my best quick guesses by function name).

- _PyRun_InteractiveLoopObject
- PyRun_InteractiveOneObjectEx
- interactive_rule
- statement_newline_rule

If anyone can point me in the right direction, that'd be great, and I think I can work on this one tomorrow if that's all right!
