That explains why I saw this using my setup.
But I don't see how it explains why I saw it using
emacs -Q, even after having used my setup in a separate
session, and even if that separate session is still open.

That's still a mystery to me.  And the fact that I
reported the same thing twice, years apart (having
forgotten the first report) supports the description
that I gave (both times): I saw the problem with emacs
-Q (in multiple versions even), but later couldn't
repro it.

Anyway, I'm fixing my version of I`nfo-find-node-2'...
