    [grog]: Improve unrecognized option diagnostic.
    
    * src/utils/grog/grog.pl (handle_args): Complain less noisily and more
      comprehensibly when given unrecognized groff options.
    
    Before:
        $ grog -A
        /usr/lib/groff/grog/subs.pl 302: unknown argument -A
        groff -A -T ps -
    
    After:
        $ ./build/grog -A
        grog: warning: unrecognized groff option: -A
        groff -A -T ps -
