phabricator: prevent posting obsolete commits
I don't see why this would be useful in the first place. But I had a coworker
submit a single commit that was not a branch head, and the result was to orphan
its child and keep the original commit visible. He then did up arrow + Enter,
and it happily created a new review (since the URL isn't amended into the
original commit specified on the command line) and a new successor, resulting in
a local divergence. I'd like to fix the issue with creating orphans, but this
is simple enough to prevent on its own.
