Almost every change on emacs-23 is intended to trunk too. Right now
those changes that are exclusive to emacs-23 must be flagged

will work on common-fixes, except for those cases where they would flag
the change as belonging to emacs-23 only. Not so hard, IMO.

trunk. That's all.

The problem was that commits intended to emacs-23 were merged into
trunk. Yes, people can do all kinds of mistakes, but no script will
magically avoid them.

You are missing the point. common-fixes will eliminate the need for
cherry-picking (and for examining each commit on emacs-23 before merging
into trunk). The maintainers save time and the VC history is consistent
(with commits maintaining its identity on the branches where they are
