  56 "git what's new", show descendants of a specific commit. For example,
  57 after "git fetch", list all new commits.
  58
  59 Usage: $progname [options] [commit] [git_log_args]
  60
  61 Options:
  62
  63   -h, --help
  64     Show this help.
  65   -p, --patch
  66     Use extended format with patch.
  67   -q, --quiet
  68     Be more quiet. Can be repeated to increase silence.
  69   -v, --verbose
  70     Increase level of verbosity. Can be repeated.
  71   -w, --word-diff
  72     Same as -p, but use word diff instead
  73   --version
  74     Print version information.
  75
  76 If commit is not specified, use HEAD. To use git_log_args, a
  77 commit/branch/tag/whatever has to be specified as \$1.
