[New-bugs-announce] [issue13938] 2to3 fails to convert types.StringTypes appropriately

New submission from Mark Hammond <skippy.hammond at gmail.com>:
test_types.py converts "types.StringTypes" to "str" - but types.StringTypes is a tuple, so expressions like "type(x) in type.StringTypes" fails after conversion with "TypeError: argument of type 'type' is not iterable"
Attaching a fix and test.
Note that the fixer still seems "strange" after this fix - types.StringType gets converted to "bytes" but types.StringTypes uses str. This means the expression "type.StringType in type.StringTypes" evaluates to True in 2.x but False once converted - however, that should probably be tackled in a different bug - the fact the expression now causes a TypeError once converted is more blatantly wrong and the focus of this bug.
