doc: Make --check-sigs more prominent. 

--

It seems people are using --list-sigs instead of --check-sigs and do
not realize that the signatures are not checked at all.  We better
highlight the use of --check-sigs to avoid this UI problem.

The status of the verification is indicated by a flag directly following
the "sig" tag (and thus before the flags described above for
@option{--list-signatures}). A "!" indicates that the signature has been
successfully verified, a "-" denotes a bad signature and a "%" is used
if an error occurred while checking the signature (e.g. a non supported
algorithm).
