Implement Mark Favas's suggestion. There's a clear bug in _group():

its first return statement returns a single value while its caller
always expects it to return a tuple of two items.  Fix this by
returning (s, 0) instead.

This won't make the locale test on Irix succeed, but now it will fail
because of a bug in the platform's en_US locale rather than because of
a bug in the locale module.
