In general, you usually have a parent of a branch. That was the one that
you first branched/pulled/merged/etc from.
It is stored in .bzr/parent

I don't think we ever created a command to show this to the user, though
we probably should.

But it is the default for all pull/merge/etc commands. So if you do:

bzr branch http://other local
cd local
<hack hack commit hack hack etc>
bzr merge # This will default to http://other

Does that help you?
