Update on pull -u when heads were closed (fixes issue666). Patch written by Benoit Boissinot. This should probably be improved in the future to handle long-living branches, as joining two "other" heads will switch to that new head. But this is not a new problem, as adding to the "other" head would have switched to that new head, too.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help
