@sueloverso: Lint is unhappy about using "found", and is concerned we can use `op` when it hasn't been set.   I don't think there's a bug here, but I had to stare long enough to convince myself of that, I rewrote it in terms of the op variable.  As I said, feel free to throw this away if you dislike it.

There's the usual trivial change because WT_ERR isn't needed.
