docs: Own "dumb" reimplementation of textwrap.wrap().
  
      This is because calling .wrap() on bigger strings can take a LOT of
      processor power. And I mean like 8 seconds of 3GHz CPU just to wrap 20kB of
      text without spaces.
  
      Args:
          text (str): Text to wrap.
          columns (int): Wrap after `columns` characters.
  
      Returns:
          str: Wrapped text.
