Can you remember a reason for that?  It would have helped if the tests had
comments explaining why in the first place...

I just looked at test_clone_bzrdir_repository_branch_both_under_shared, and
after spending a solid ten minutes figuring out exactly what it actually does
and writing the comments it should have had in the first place, I've found:

  * the name of the test doesn't actually correspond to what it does,
  * parts of the test still don't make sense to me, and I suspect it's because
    it's not doing what the author thought it was, and
  * it's entirely reasonable for this test to use "tree.branch.repository"
    rather than "tree.branch.bzrdir.open_repository()" as far as I can tell.

I can do a similar audit of the other tests in this file, but it'll take a
little while.  Are you sure there's a reason to worry here?
