This issue(s) seem to need a variety of reporting contexts
for coverage. My coverage at this point is more of a
check if something reverted for my type of context but when
it started my context was a failure case.

I'm no longer testing a context based on the earlier patch
(before its commital) but now caught up to recently enough
on the ThreadRipper to have screen.textmode be the intended
means of control:

# ~/fbsd-based-on-what-freebsd-main.sh mm-src
b1ea63e2e3c92d1346af067f5cf609e3e062f8b9

fa0b97dbe6e1 b1ea63e2e3c9 (HEAD -> mm-src) mm-src snapshot for mm's =
patched build in git context.
FreeBSD FBSDFHUGE 13.0-CURRENT FreeBSD 13.0-CURRENT =
mm-src-c255637-gfa0b97dbe6e1 GENERIC-NODBG  amd64 amd64 1300133 1300133

For this vintage of my context . . .

screen.textmode=3D"1" works. (With the huge, blocky font on the =
1920x1200
display. But nothing significant about that is recently changed.)

screen.textmode=3D"0" works, including with screen.font=3D"8x16" . There
is a difference, in that it displays some material at the very beginning
that it was not displaying since the recent problems started (until now
or so). This initial material displays in screen.textmode=3D"1" style =
before
the display switches to the screen.textmode=3D"0" style of display for =
alter
output. (I'm not complaining, just noting the visible sequence.)
