Test hg pull --rebase degrades gracefully if rebase extension is not loaded
  $ hg init remoterepo
  $ cd remoterepo
  $ mkcommit root
  $ hg book bookmarkonremote

  $ cd ..
  $ hg clone -q remoterepo localrepo
  $ cd localrepo

Make sure to enable tracking
  $ hg book bmtrackingremote --track default/bookmarkonremote
  $ hg pull --rebase > /dev/null
  hg pull: option --rebase not recognized
  (use 'hg pull -h' to get help)
  [255]

Tests 'hg pull --rebase' rebases from the active tracking bookmark onto the appropriate remote changes.
  $ setglobalconfig extensions.rebase=
  $ cd ../remoterepo

Create remote changes
  $ mkcommit trackedremotecommit
  $ hg up -q -r 0
  $ mkcommit untrackedremotecommit
  $ printdag
  @  untrackedremotecommit |  |
  |
  | o  trackedremotecommit | bookmarkonremote |
  |/
  o  root |  |
  

Create local changes and checkout tracking bookmark
  $ cd ../localrepo
  $ hg up -q bmtrackingremote
  $ mkcommit localcommit
  $ printdag
  @  localcommit | bmtrackingremote |
  |
  o  root |  | default/bookmarkonremote
  
Pull remote changes and rebase local changes with tracked bookmark onto them
  $ hg pull -q --rebase
  $ printdag
  @  localcommit | bmtrackingremote |
  |
  | o  untrackedremotecommit |  |
  | |
  o |  trackedremotecommit |  | default/bookmarkonremote
  |/
  o  root |  |
  
Tests 'hg pull --rebase' defaults to original (rebase->pullrebase) behaviour when using non-tracking bookmark
  $ hg debugstrip -q -r 3 -r 2 -r 1
  $ hg book -d bmtrackingremote
  $ hg book bmnottracking
  $ mkcommit localcommit
  $ printdag
  @  localcommit | bmnottracking |

Tests the behavior of a pull followed by a pull --rebase
  $ cd ../remoterepo
  $ hg up bookmarkonremote -q
  $ echo foo > foo
  $ hg add foo -q

  $ hg book -t default/bookmarkonremote tracking
