Gustavo,

Just a quick note on compatibility.  As I mentioned, the PCRE 
rule is that groups in negative asserts do not match.  So, with 
Python 2.2, you get this result using pre:

>>> pre.match('((?!(a)c)[ab])*', 'abc').groups()
('b', None)

Although I understand your argument, I'll just say that I 
personally think it would be better to move toward compatibility 
with pre (which after all was the official Python regex engine 
before sre), rather than to remain partly compatible with Perl.

Thanks for reviewing my patches and fixing the bugs!
