LONG_USAGE='             __*__*__*__*__> <upstream>

  fork-point
            \__+__+__+__+__+__+__+__> <head>

Each commit between the fork-point (or <limit> if given) and <head> is
examined, and compared against the change each commit between the
fork-point and <upstream> introduces.  If the change seems to be in
the upstream, it is shown on the standard output with prefix "+".
Otherwise it is shown with prefix "-".'
