Hi Eli, Spencer,

I've reviewed the code.  I understand Spencer's rationale for the
small refactoring and I'm OK with it.

However I didn't test.  I'd say it's better for this new capability to
go to master, though with some minimal testing (say, at least in tty
as well as graphical mode) it shouldn't be really dangerous for
emacs-29 either.
