    m4/groff.m4: Fix Savannah #63808 (1/3).
    
    * m4/groff.m4 (GROFF_CHECK_GROPDF_PROGRAMS): Better characterize
      gropdf's reduced function, pointing out the ways in which it would be
      more useful if the dependencies were met.
    
      (GROFF_URW_FONTS_NOTICE): Identify 'U' as the foundry name gropdf uses
      for the URW fonts.  Confirm continuing availability of most recent URW
      fonts release; bump date.
    
    Fixes <https://savannah.gnu.org/bugs/?63808>.  Thanks to Deri James for
    the report and extremely helpful pseudocode.
