[issue4806] Function calls taking a generator as star argument can mask TypeErrors in the generator

I believe I encountered this issue today on Python 2.7.14 (https://ci.appveyor.com/project/jaraco/jaraco-windows/build/31/job/lenh5l4dcmj137b9). In this case, I have an iterable (in itertools.imap) that raises a TypeError when evaluated, not a generator.

The issue doesn't happen on Python 3, where 'map' is used instead of itertools.imap.

Does this patch need to be extended to support any iterable?
