<p dir="auto" style="color: #3a383f; margin: 0px 0px 1rem;" align="initial">The branch answers the four small points of my second review. I fetched
the head into my work tree and diffed <code style="font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; margin-top: 0px; font-weight: inherit; overflow-wrap: break-word; white-space: break-spaces; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; word-break: keep-all; padding: 0.125rem 0.25rem;">2c07609b</code> against <code style="font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; overflow-wrap: break-word; white-space: break-spaces; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; word-break: keep-all; padding: 0.125rem 0.25rem;">8a90da88</code>, the
commit which I built and tested in four configurations. Only two comment
blocks and the commit message differ. No code moves. The test result of
my second review stands.</p>
<h2 dir="auto" style="margin-top: 20px; margin-bottom: 10px;" align="initial">One sentence of the commit body names the wrong year</h2>

and stands at 2514-05-30T01:53:03Z. A set to the year 2500 works. Year
2400 is the limit which this commit chooses for margin. Name the wrap year
in that sentence.</p>
