Flags in parentheses are mutually exclusive. Logic is taken from commands.py:
selactions = [k for k in ['delete', 'rename', 'list'] if opts.get(k)] if len(selactions) > 1: raise error.Abort(_('--%s and --%s are incompatible') % tuple(selactions[:2])) ... if rev and action in {'delete', 'rename', 'list'}: raise error.Abort(_("--rev is incompatible with --%s") % action) if inactive and action in {'delete', 'list'}: raise error.Abort(_("--inactive is incompatible with --%s") % action)
