We still want that message to be moved to the end of the minibuffer
when that minibuffer is active, and users may still want to be able
to silence some of those messages.

Apparently, we do run ELisp code from `maybe_quit` via the GUI's event
handling (according to Po Lu, not just under macOS but also under X11),
so maybe we should strive to make it "safe" to run ELisp from `maybe_quit`
(and hence atimers).
It's inherently dangerous since it amounts to preemptive concurrency, so
by "safe" I mean that we should strive to make it safe with some
side-conditions about the risks of concurrency bugs.
