Couldn't apply cleanly the patch, as it appears to be a diff in other
format.
Anyway, applied it by hand, and now I attach the correct svn diff.
The test cases run ok with this change, and the problem is solved.
Regarding the delay introduced, I tested it with:
$ ./python timeit.py -s "import re;r=re.compile('a?a?a?a?a?aaaaa')"
"r.match('aaaaa')"
Trunk:
100000 loops, best of 3: 5.4 usec per loop
100000 loops, best of 3: 5.32 usec per loop
100000 loops, best of 3: 5.41 usec per loop
Patch applied:
100000 loops, best of 3: 7.28 usec per loop
100000 loops, best of 3: 6.79 usec per loop
100000 loops, best of 3: 7.00 usec per loop
I don't like that. Anyway, I do NOT trust for timing the system where
I'm making the timing, so you may get different results.
Suggestions?
