It might even have one or two of my own bug reports in there.  :-)

I haven't tried so-long-mode (it seems to have become available only
with emacs-27), but it appears from its description that it would also
DTRT in my particular case.

I never use the console and I have seen exactly the same problem in
emacs-X11 (with DISPLAY on a Linux box) and emacs-nox (both over ssh an
in mintty locally).  I don't have another system with emacs-27 yet, but
I expect that to be unrelated to Cygwin.
