Emacs doesn=E2=80= =99t display any message, I=E2=80=99ve tried catching it with
=E2=80=98(= setq debug-on-message "Too")=E2=80=99 but got nothing.

I=E2=80=99ve found the Info = node on [1] but not in my Emacs nor on [2].
Could it be that both the no= de and the message are new features of
versions > 27.2?
