+"""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)
