 Pushing a bookmark should only push the changes required by that
 bookmark, not all outgoing changes:
   $ hg clone http://localhost:$HGPORT/ addmarks
   requesting all changes

   adding manifests
   adding file changes
   added 5 changesets with 5 changes to 3 files (+2 heads)
   2 new obsolescence markers
   updating to bookmark @
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ cd addmarks

   $ hg add foo
   $ hg commit -m 'add foo'
   $ echo bar > bar
   $ hg add bar
   $ hg commit -m 'add bar'
   $ hg co "tip^"
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   (leaving bookmark @)
   $ hg book add-foo
   $ hg book -r tip add-bar
 Note: this push *must* push only a single changeset, as that's the point
 of this test.
