  53 Options:
  54
  55   -e, --exit-val

  60   -h, --help
  61     Show this help.
  62   -i, --ignored
  63     Also wait if there are any ignored files in the repository.

  65     Be more quiet. Can be repeated to increase silence.
  66   -u, --untracked
  67     Allow untracked files in the repository.
