Nope, I was right the first time. The (mis-)behavior documented in comment #0
goes back to _groff_ 1.22.3 at least.
What happened was, I wrote a regression test that relied on the new `pwh`
request, and no news looked like good news.
Problem confirmed on _groff_ 1.24.1, 1.24.0, 1.23.0, 1.22.4, and 1.22.3 with
the following script.
