SYNOPSIS
	void add_xverb(string str)

DESCRIPTION
	This function is connected to the add_action() function. It will set up
	the command <str> to trigger a call to the function set up by the
	previous call to add_action().

	add_xverb() differs from add_verb() in that only leading characters
	of the input line must match with <str>. It basically is the same
	as setting <flag> in add_action().

	USE THE Nightfall II mudlib LFUNS INSTEAD.
