@jh7370 Sorry to be needy, but could you give this PR another look? As a relatively new contributor, I am nervous about doing the right thing.

That said, I profusely apologize for using a force push to bring in an updated base branch -- my muscle memory took over and I pressed Enter before I realized my mistake. I do, sincerely, appreciate your feedback and _promise_ that I took it to heart and will not make the same mistake again!
