* configure.ac, doc/man/Makefile.am - Add check for HTML output support in GNU
          groff.  Fixes Savannah bug #24461: build traps on groff.  Also, add installation
          of html-ized man pages to $datadir/nano/man-html, since we should probably
          install files we went to all the trouble of generating.
