Hmm.  I read Peter's message as agreeing with Andres rather than with
you.  And I have to say I agree with Andres as well.  I think it's
weird to back a commit out only to put a bunch of very similar stuff
back in.  Even figuring out what you've actually changed here seems
rather hard.  I couldn't get github to give me a diff showing your
changes vs. master.
