Sure, I'll port it to Python2.2.  I'm surprised it dod not apply 
cleanly there, but then I don't know the history of previous 
patches (like when lastmark_restore was introduced).  I guess 
copying all sre code will be the first thing to try.  How do I get a 
dev version of Python 2.2? 
 
Yes, the *? code is all Greg Chapman's.  He sent it to me the day 
I announced my volunteering to maintain the sre code.  I wrote 
the test cases for it, and used it as a great way to learn my way 
through the code.
