The doc string of `emacs-mail-verify' does not say how it
indicates that the signature is valid, or how it indicates
that the signature is not valid.
Would someone please add that to its doc string?

I guess you meant epa-mail-verify?
> Would someone please add that to its doc string?
Not sure what you expected the doc string to say. Would the below be
enough?
Verify OpenPGP cleartext signed messages in the current buffer.
The buffer is expected to contain a mail message.
If the verification fails, the command signals an error.
The last sentence describes the following snippet from
epa-verify-region, which epa-mail-verify calls:
(unless (epg-context-result-for context 'verify)
(error "Unable to verify region"))
There are also other reasons to signal an error, e.g. if there are no
"-----BEGIN PGP SIGNED MESSAGE-----" line. But eventually, all of the
problems cause an error.
If this is somehow not detailed enough, then I'm afraid someone else,
who knows the code, will have to improve the doc string, because I
could see no clear description in the code what values could the
context-result have and what is the meaning of each result. Maybe I
missed something.

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?

Thanks, I installed a change along those lines.

I don't know how to describe success in this case, except as the lack
of an error.

> on success?
It says "Verifying...done", which I think is enough (and quite
standard in Emacs).
> Do some people run this function from a hook for every message and
> want to see output only in case of failure?
See above: it displays a message in case of success as well.
> Should it a value indicating success or failure?
I don't know. The values of the relevant functions don't seem to be
documented.

I agree, that should be enough.
(I didn't know it did that.)
Perhaps document that in the doc string:
On successful verification, displays ""Verifying...done" in echo area.
Perhaps it should return t if it succeeds in verifying, and nil otherwise.

That sounds redundant, as the message seems to speak for itself?
> Perhaps it should return t if it succeeds in verifying, and nil otherwise.
I thought about it, but the functions it calls don't have their return
value documented, so doing that seems to require a serious surgery of
the code with which I'm not familiar.
