"""Fixer that cleans up a tuple argument to isinstance after the tokens
in it were fixed.  This is mainly used to remove double occurrences of
tokens as a leftover of the long -> int / unicode -> str conversion.

eg.  isinstance(x, (int, long)) -> isinstance(x, (int, int))
       -> isinstance(x, int)
