[Python-Dev] [#527371] sre bug/patch

[Gustavo Niemeyer]

Patch #527371, from Greg Chapman, seems to be pretty obvious, and is
laying around for quite some time. The same pattern even happens in
a few other places in the sre module. I suggest we apply it, including
the fixes for lastindex mentioned in the discussion.

As a minor observation, I'd include the "state->lastmark = lastmark;"
line inside the 'if' block when applying, as every other occurence of
this algorithm. No big deal, but saves a few cycles.
