That's fine. No rush. I've had local workarounds for this for a very
long time, so I can be patient for a little longer. =)

I adopted the wording as for git commit and since the behavior is
exactly the same, it seemed best to stay consistent with that. My
interpretation of "bypassed" is equivalent to "unused" or "ignored",
though "ignored" in this case relating to their existence rather than
return value.

Either wording is fine with me, so if you feel strongly I can reword
this. In that case it might be worth updating the git commit
documentation as well to avoid the same ambiguity.

Yes, that's a good point. I've updated both tests to check that the
patch has been applied and the scripts haven't been run.

Thanks,
