I don't either, not being a -commiter I don't really follow that area much :-)

Yep, I agree and as you pointed out it does not work anyway (in the
sense of being able to keep the same commit id/hash) because you end
up needing to change things.

I dont think it would be to hard to code that up (main worry is it
might be dog slow).  BTW the point about git cherry-pick -x is that it
includes the original commit hash in the commit message.  That way we
don't  have to do any guess work based on commit time and log message.
