Actually, none of the "settings" were getting cleared for the problem case, so this comment isn't completely accurate.

Also, the wording of the existing comment was confusing.

Suggested re-wording for this comment:

Not all stub configuration is being deleted. (It is also possible that none of the stub options requested for deletion match any current configuration. In that case, no stub configuration is being deleted.)

The proposed code change and corresponding test results look good.

I am posting only a request for re-wording of the comment related to the modified section of code.

[kerry-meyer]

Thanks for the incremental edit of the comment for the affected section of code.

All current proposed changes and test results look good.

Thanks for finding and fixing this bug.

Approved.
