You will see that the same code is duplicated, more or less, in
msdos.c, beginning at line 1612. That is why I thought the same
problem could happen there, and that is why I was bothered by the fact
that the fix was only applied to builds that define
HAVE_WINDOW_SYSTEM.
Meanwhile, I've built an MSDOS port of Emacs 22.0.91 and found I
couldn't reproduce the original problem in it. So I guess the issue
of whether the same fix should be applied to the MSDOS port can now be
closed.
As to the concerns expressed by Yamamoto Mitsuharu, I would also
suggest that a redisplay expert looks into them.
