/*
 * numbered_command: does (hopefully) the right thing with the numbered
 * responses from the server.  I wasn't real careful to be sure I got them
 * all, but the default case should handle any I missed (sorry) 
 *
 * The format of a numeric looks like so:
 *
 *	:server-name XXX our-nick Arg1 Arg2 Arg3 ... :ArgN
 *
 * The last argument traditionally has a colon before it, but this is not
 * compulsary.  The BreakArgs function has already broken this up into 
 * words for us, so that what we get, looks like this:
 *
 *	server-name	-> 	from parameter
 *	XXX		->	comm parameter
 *	our-nick	->	ArgList[0]
 *	Arg1		->	ArgList[1]
 *	Arg2		->	ArgList[2]
 *	...			...
 *
 * BUT!  There's a wrinkle in the ointment.  The first thing we do is slurp
 * up ArgList[0] (our-nick) and put it in 'user'.  Then we increment the 
 * ArgList array, so what we actually end up with is:
 *
 *	server-name	-> 	from parameter
 *	XXX		->	comm parameter
 *	our-nick	->	user
 *	Arg1		->	ArgList[0]
 *	Arg2		->	ArgList[1]
 *	...			...
 *	ArgN		->	ArgList[N-1]
 *	NULL		->	ArgList[N]
