The obvious thing to do here is separate the notion of "We didn't find a
parenttip" from "The parenttip has a false value".

a changectx has the boolean value of the node it reperesents, just a parenttip
of the implicit -1 rev (the null node) is false.

If we were to check for None explicitly, this would go away.

The side-effect would be that an empty workspace (a workspace with no already
committed changes) would be related for our purposes to any other workspace.

I suspect this isn't actually problematic (on first commit they cease being
related).

Assuming the above is correct, I'd like opinions on whether this seems like the
correct thing to do.
