Summary: 2.3a1 computes lastindex incorrectly

Initial Comment:
In Python 2.[012], the code

import re
exp = re.compile("(?P<NCName>[a-zA-Z_](\w|[_.-])*)")
print exp.match("namespace").lastgroup

prints "NCName". In Python 2.3a1, it prints "None". The
problem is that last index is 2, instead of 1, as it
should be.
