docs: used by recursive functions to specify which level to turn a bool on in
      counting down yields True, True, ..., False
      counting up yields False, False, False, ... True
  
      Args:
          count_or_bool (bool or int): if positive and an integer, it will count
              down, otherwise it will remain the same.
  
      Returns:
          int or bool: count_or_bool_
  
      CommandLine:
          python -m utool.util_str --test-_rectify_countdown_or_bool
  
      Example:
          >>> from ubelt.util_format import _rectify_countdown_or_bool  # NOQA

          >>> a1 = (_rectify_countdown_or_bool(2))

          >>> a4 = (_rectify_countdown_or_bool(-1))
