Oops, yes.

That is better, becauee it gives enough information to deduce what
indicates success.  But the user should need to do any deduction about
that, let alone read code and guess what some other functions do.

To make the doc string truly clear, it should say explicitly what
indicates success.  That way the user can know, rather than just
supposing.

Should the function be changed to display a message, "Signature verified",
on success?

Do some people run this function from a hook for every message and
want to see output only in case of failure?

Should it a value indicating success or failure?
