    [mdoc]: Use more reasonable fallback title length.
    
    * tmac/mdoc/doc-nroff (doc-setup-page-layout): Set the title length to
      the configured line length (register `.l`) if register `LT` is not
      defined.  This keeps the title length from being set to 78n when the
      line length is not, preventing the output from looking silly.
