[Import-SIG] PEP 420 issue: extend_path

[Nick Coghlan]

How is starting an accumulator and returning it unconditionally *more*
complicated than "if you don't find any portions return None".

"Why should I do that, what happens if I just return my empty container
instead?"

"Oh, that's the same as returning None."

It makes no sense. We *have* to handle the empty iterator case regardless.
Allowing None *as well* is just plain redundant.

Regards,
Nick.
