Martin: Thanks so much for your thoughtful answer. You've obviously
given this more thought than I have. From your answer, it does indeed
sound like string_format.h needs to be removed from stringlib. I'll have
to think more about formatter.h.

On the other hand, not having this code in stringlib would certainly be
liberating! Maybe I'll take this opportunity to clean it up and simplify
it now that it's free of the stringlib constraints.

Eric.
