Just to continue a bit, Then, if I had a headline like "Nero Burning Rom Released Today," I'd wind up with:

Nero Burning
Burning Rom
Rom Released
Released Today

And all except the first would be deleted because they are redundant with the first, or with subsequent redundancies...???? (Hmmmm.... might want it to work backwards... deleting the first initially.... So redundancies would be matched....??? Not sure that's necessary...)
