Sounds to me like the maintainer should figure out how to delegate some
of the load a bit. Or just go on vacation and ignore all mails. I hear
stress isn't good for you.

That's what all patches are. No should be applying unreviewed patches
blindly.

Also often a revert is a perfect way to handle regressions. It gets
the angry users off your back ASAP allowing you to fix the bug
properly without having to rush it. I only wish all regression I've
caused would have been caught early enough for a revert to apply
cleanly. 

Even if the revert isn't applied the fact that the mail has the 
offending code right there makes the disussion easier. No need to
git fetch; git show <copy paste sha>; copy paste some code snippets
into the mail, etc.).

Calm down. No one is out to revert all your patches.

Maybe you can propose a new git-regression tool then? And document that
you want bugs reported using it? Ideally I'd say it should do almost
exactly what git revert does except s/revert/regression/. Though I
suppose it could include the original diff instead of the reverse.

Now, how about we stop this pointless "logic" discussion and
focus on the techinal stuff from now on?
