7777-7778 => 7777-78
not -8 ?
Sorry for the algorithm confusion. It was late, and I probably should 
have explained that the algorithms vary.  So, sometimes they say that, 
in the above case, it ought to be collapsed to 7777-8, while in other 
cases 7777-78.  I'm happy to just get one of them correctly working for 
the time being though!
I had implemented a hack that just compared the substrings, but I'll 
try the more general solutions posted here.
Thanks all!
