Summary: Backport of recent sre fixes.
Initial Comment:
This patch should reproduce, in the release22-maint
branch, an exact copy of the sre code currently in the 2.3
branch, with the single exception of the declaration of the
module init function. All future patches should apply
cleanly to both 2.3 and 2.2 branches.

Gustavo,
If I understand correctly:
* The backport to 2.2 done by just copying the code from 2.3 is
not the problem, but merely needs to be repeated in light of
changes made, by you and Martin, to 2.3 in that last several
days.
* The "Greg Chapman's patch" you refer to in the checkin
comment of revision of 2.91 of _sre.c is from before I came
on-board, and is not the MIN_REPEAT_ONE stuff I got from him
and gave to Guido to produce revision 2.88.
* That previous patch of Greg's (revision 2.84 of _sre.c) caused
some bugs (or at least discrepancies) which you have now
resolved in the last day or two.
* The MIN_REPEAT_ONE stuff of Greg's is not at issue.
* The LASTMARK_SAVE()/LASTMARK_RESTORE() calls were
added (quite recently) to fix some bugs, and perhaps are needed
in other spots if we were to be clever enough (or unlucky
enough) to provoke them.

Why does the patch remove partial history?

No problems. I'll check the patch and workout any issues
with Gary.
Thanks for pointing me this.

Assigning this to Gustavo Niemeyer, who found some problems
with this code in 2.3. Gustavo, would you mind working with
Gary on backporting this properly?
