  #   mirror    — force-update branches and prune what upstream deleted.
  #               What an imported repo has always done, and what
  #               "mirror of upstream" means.
  #   reconcile — fast-forward what can fast-forward, leave everything
  #               else alone and report it. The mode an adopted repo
  #               gets, because it has history of its own.
