The upshot is that bzr co should set the parent pointer as well as the 
bound branch, so that pull works by default for checkouts (and fails if 
you've diverged from the bound/parent branch).

Incidentally, does it make sense for the parent branch and bound branch 
to be different? What use cases are there for that, since it is 
obviously a potential source of confusion?
