 * cmd_away() - Added 14 Dec 1988 by jto.
 *            Not currently really working, I don't like this
 *            call at all...
 *
 *            ...trying to make it work. I don't like it either,
 *            but perhaps it's worth the load it causes to net.
 *            This requires flooding of the whole net like NICK,
 *            USER, MODE, etc messages...  --msa
