Oh, I'm relaxed.  Believe me, Man. ;-)

I already welcomed that, in a previous message.
It's helpful to tell users how many completions
there are.

(I suggested that the *Completions* mode-line
might be a better place for it.)

My message wasn't about your addition of the
number of matches at the top of *Completions*
(when there _are_ matches).

I don't see "Possible completions are:" when there
are no completions.  What I see is that window
*Completions* is removed when you try to complete
a pattern that has no matches.

(Granted, I'm looking at the latest release, 27.2,
not any new work-in-progress.  But you say this
thing I don't see has been there forever, so I'm
perplexed.  We must not be smoking the same thing.)

My point was that, compared to the vanilla, age-old
behavior of removing the *Completions* window when
you try to match an unmatchable pattern, a proposed
new behavior of continuing to show *Completions*,
but with a message at the top saying "0 possible
completions" (or any other wording of that), sounds
like a step backward, to me.  That's all.  Just one

(And I don't even use the vanilla *Completions*
behavior.  I just happen to care about Emacs beyond
my own use of it.)

I don't want to put anything there.  I'm asking why
we'd want to show a buffer that lists no completions,
instead of just removing that window.  I'm asking
why that would be an improvement - or even a good
option to offer.
