Thank you!

I thought about that, but I decided against it because of the security risk:
from evil_module_of_doom import something
Just tab-completing the name "something" shouldn't run the evil module. I
suppose I could add it as an optional feature, defaulting to off. Or try
parsing the source code.

By default, it should indent with an actual tab character, which most
terminals treat as 8-spaces wide. But you can change that by setting
completer.indent to whatever string you want. Are you sure it is using
actual spaces?

Weird. It shouldn't be adding a close quote. Mind you, there appears to be
at least one other bug in the file name completion, so I need to work on
that soon.
However, I can reproduce the bug, so I'll work on that too. Thank you for
the report!
