Note: Something went wrong between me and Git. I intended to address
review comments only by adding commits (e.g., rather than by, say, deleting
any), in order to avoid obscuring earlier comments here in the GitHub
conversation. However, for some reason, more than just the last four update
commits (with "Upd.") show up as being added today. I apparently re-ordered
some commits during rebasing.
