When I tried this the pre-lock hook gets run regardless, but if the
user doesn't pass --force, the lock won't be stolen. Even if the hook
exits with 0.

But I see that you still have a problem. During the pre-lock you've got no
way of knowing if the lock will succeed, but in the post-lock hook you've
got no way of knowing who the lock was stolen from so you can't send
an email directly that person.

Does that make sense, or have I missed something? I'm sorry, but
I don't think I've helped you solve the problem either way :)
