This test demonstrates how Hg works with remote Hg bookmarks compared with
remote branches via Hg-Git.  Ideally, they would behave identically.  In
practice, some differences are unavoidable, but we should try to minimize
them.

This test should not bother testing the behavior of bookmark creation,
deletion, activation, deactivation, etc.  These behaviors, while important to
the end user, don't vary at all when Hg-Git is in use.  Only the synchonization
of bookmarks should be considered "under test", and mutation of bookmarks
locally is only to provide a test fixture.

- change b1 on local repo
- introduce b2 on local repo
- introduce b3 on remote repo

- introduce b4 on a new rev on the remote

As of 2.3, Mercurial's outgoing -B doesn't actually show changed bookmarks
It only shows "new" bookmarks.  Thus, b1 doesn't show up.
This changed in 3.4 to start showing changed and deleted bookmarks again.
