The user experience is exactly the same than before.  Just that now
there is an option to change, suppress or/and get a counter with the
total number of completions where there was before just a bit
superfluous hard-coded message: "Possible completions are:"

That's it. Everything else is exactly the same. As usual, I am not doing
rocket engineering here; I am just adding something simple and obvious
that nobody wanted to give any attention before; in spite of many more
experienced lispers like you could implement this in 30 minutes two
decades ago ;p.

Because the original message was: "Possible completions are:" and it has
been there since ever without hearing your complains about that the
completions are not IMpossible.

I don't care anything about one word at all and if the user doesn't like
the word or you want to put there "Drews completions are:", at least now
you have an option to customize it as you prefer...
