Re: collapsing number ranges

If that's not what you're after, show us the XML of some more examples
and try to put the algorithm that you want into English or
pseudo-code.

FIRST NUMBER		SECOND NUMBER		EXAMPLES
1-99				use all digits			3-10, 71-72, 96-117
100 or multiples		use all digits			100-104,
of 100								1100-1113

101-109			use changed part	 only		101-8,
201-209, etc.							1103-4				
110 through 199		use two or more digits		321-28,
210-299, etc.		as needed				498-532,
									1087-89
		
				But, if three digits change	1496-1504
				in a four-digit number,	2787-2816
				use all four
