We also put the key information after the message and not between the
user id and the last used info like here:
gpg: Verified 7 messages signed by "Werner Koch <werner@eifzilla.de>"
in the past 4 days, 16 hours.
The most recent message was verified 3 days, 13 hours ago.
(key: 8061 5870 F5BA D690 3336 [...] 1E42 B367, policy: auto)
This also makes the key info a separate translatable string.
Further a compact version of the fingerprint (hex w/o spaces) is
printed in some messages.

Extracting the keyid form the fingerprint is not a good idea because
that only works for v4 keys. It is also better to first read the key
and then extract the keyid from the actual available key.
The entire trusted-key stuff should be reworked to make use of
fingerprints.
