I don't understand how it happened, but apparently I got a merge commit
backward and merged 3.6 into 3.5 and pushed it without realizing what
had happened. If anyone has any clue how to reverse this cleanly,
please let me know. (There are a couple people at the sprints looking
in to it, but the mercurial guys aren't here so we are short on experts).
My apologies for the mess :(
