The 2to3 except fixer will be failed with this code:

try: raise TypeError
except TypeError, x:
pass

with this code, 2to3 will produce an empty diff, i.e. it fixes nothing.

But when change it to the following, 2to3 works again:

try:
raise TypeError
except TypeError, x:
pass

with this, 2to3 will provide a correct diff.
