One specific corner case: if one has a shared repo, location <repo>,
and a branch below <branch>, then one accidentally pushes to <repo>
instead of <repo>/<branch>. This results in a new branch created in
the same location as <repo>, so the new branch can't be removed by
deleting the directory. I think that deleting the <repo>/.bzr/branch
directory will remove the branch - is that correct?
