docs: Fill a single paragraph of text, returning a new string.
  
      Reformat the single paragraph in 'text' to fit in lines of no more
      than 'width' columns, and return a new string containing the entire
      wrapped paragraph.  As with wrap(), tabs are expanded and other
      whitespace characters converted to space.  See TextWrapper class for
      available keyword args to customize wrapping behaviour.
