Yeah, anyone that pulled the bad change has to manually repair their
repo. The proper thing to do is to just reverse all the changes. As
you found out git revert has problems if there is a merge involved
because it doesn't know which parent tree is 'trunk'; but it is still
possible to create a patch manually. (There is probably some git magic
to tell revert what to do, but I don't know it.)
As a rule you should only get rid of commits completely while they
are still only in your local tree. After that you want to commit
something new to do undo the damage.
