Good point.  We shouldn't emit such messages when we're in the
minibuffer (or we should emit them differently, so as not to hide
the minibuffer text, e.g. like minibuffer-message does).

Let's first silence (unconditionally) the messages when in
the minibuffer.  We'll see later if messages still need to be silenced,
and in which cases.
