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 changesets
  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
  $ echo foo > foo
  $ 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.
  $ hg push -B add-foo --traceback

pushing a new bookmark on a new head does not require -f if -B is specified

  $ hg up -q X
  $ hg book W
  $ echo c5 > f2
  $ hg ci -Am5
  created new head
  $ hg push -B W

  $ hg -R ../b id -r W
  cc978a373a53 tip W

pushing an existing but divergent bookmark with -B still requires -f

  $ hg clone -q . ../r
  $ hg up -q X
  $ echo 1 > f2
  $ hg ci -qAml

  $ cd ../r
  $ hg up -q X

Check summary output for incoming/outgoing bookmarks

  $ hg bookmarks -d X
  $ hg bookmarks -d Y

pushing an unchanged bookmark should result in no changes

  $ hg init unchanged-a
  $ hg init unchanged-b
