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

Thanks, issue2636-20101228a.zip also resolves my compilation speed issues I had on other (very) complex regexes.

Found this one:

re.search("(X.*?Y\s*){3}(X\s*)+AB:", "XY\nX Y\nX  Y\nXY\nXX AB:")

produces a search hit with stock python 2.6.5 regex library, but not with issue2636-20101228a.zip.

re.search("(X.*?Y\s*){3,}(X\s*)+AB:", "XY\nX Y\nX  Y\nXY\nXX AB:")

matches on both, however.
