[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Jacques Grove]

Jacques Grove <aquarapid at gmail.com> added the comment:

You're correct, after the change:

regex.search(r'\d{4}(\s*\w)?\W*((?!\d)\w){2}', "9999XX")

doesn't match (i.e. as before commit 7abd9f9bb1).

I was, however, just trying to narrow down which part of the code change killed the performance on my regression tests :-)

Happy new year to all out there.
