[Gregory P. Smith]

New submission from Gregory P. Smith <greg at krypto.org>:

see the attached sample code demonstrating the problem.

basically lib2to3 fails to parse:

  dummy(**kwargs if kwargs else dict())

with an error like:

    raise ParseError("bad input", type, value, context)
lib2to3.pgen2.parse.ParseError: bad input: type=1, value='if', context=(' ', (3, 21))
