    m4/groff.m4: Tweak message format.
    
    * m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_NOTICE): Add newline at end of
      buggy Ghostscript notification, so that the multiple possible lengthy
      notices after the configuration report have blank lines separating
      them.
    
    Also quote special character escape sequence in notice.
    
    Also make code style more readable.
