docs: Format the message of the logger.
  
          You can rewrite this method to format your own message::
  
              class MyLogger(Logger):
  
                  def message(self, level, *args):
                      msg = ' '.join(args)
  
                      if level == 'error':
                          return terminal.red(msg)
                      return msg
