    [docs]: Fix environment-related content nits.
    
    doc/groff.texi (Environments):
    + Refer to "typeface", not "font", parameters: in groff, the "font" is a
      family combined with a style, or a standalone face; "typeface" is a
      more general concept and a better fit for what environments track.
    
    + Note the control character as part of the environment.
