What happens if _none_ of the files in info-lookup-alist exist?  Does
the user get any messages with your change, or will Emacs simply do
nothing visible (quietly)?  If the latter, I'm not sure the proposed
behavior is a good idea.

Btw, one alternative is to be less talkative, but not to omit the
information altogether, either: put the message into *Messages*, but
don't display it and don't sit-for.
