    m4/groff.m4: Improve URW font check.
    
    * m4/groff.m4 (GROFF_URW_FONTS_CHECK): When looking for a characteristic
      URW font by its file name, also check for "URWGothic-Book" with no
      file extension.  Avoids false negatives in URW Type 1 font detection
      when using Ghostscript 9.53.3.  Thanks to Deri James for suggesting
      the test procedure that uncovered this flaw.
