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.

Initialize remote hg and git repos with equivalent initial contents
  $ hg init hgremoterepo
  $ cd hgremoterepo
  $ hg bookmark master
  $ for f in alpha beta gamma delta; do

  > done
  $ hg bookmark -r 1 b1

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.
