BrowserUk,
You have nailed it. When I posted this, I originally thought that having each set to be processed in alphabetical sorting the sets by length in descending order would allow for this kind of optimization.

In examining the problem this post is meant to help solve further, I have realized I will not be able to process the list in descending length even if it would make things work.

Grrrrr!

Cheers - L~R
