If you want systematic scanning, we could try to come up with a script that automatically reviews all commit messages of patches since 2.1.1 whether these mention an SF bug. We could then further automate scanning to produce the number of changed lines, to exclude 'large' changes.
Slightly dangerous though -- some bugfixes were never reported to SF.
Perhaps anybody in the readership of this software already has code that does such things?
No, but you can start with Tools/scripts/logmerge.py which parses CVS log output and sorts it by date. The best way to scan for SF patch refs is probably to search for 6-digit numbers... There's too much diversity otherwise in the SF references :-( --Guido van Rossum (home page: http://www.python.org/~guido/)
