Fixed to not get false positives when the token is shorter than the actual

2002-12-03  Jeffrey Stedfast  <fejj@ximian.com>

	* broken-date-parser.c (get_tzone): Fixed to not get false
	positives when the token is shorter than the actual timezone
	string (but matches the first little bit of it).
	(datetok): Modified to properly handle when the first char of a
	token is a special char (such as a '-') that is also used as a
	token delimiter.
