SUMMARY:
The following message asks why revoked userids are not shown as such when a
keyfile is parsed by gnupg, and tries to point out dangers.

Basically, is this a bug, sorry, undocumented fature?

Why are not userid revocations displayed when gpg processes a key?
A revocation should, in my opinion, be obvious when I glance at a key.

For example:


aasmunds$bz <~> gpg --edit-key aasmunds

Why are not userids checked for revocations when a key is passed through
gnupg? It is a potential danger in that people would use the (perhaps
nonfunctional, compromised or transferred to another person) e-mail
addresses listed in a revoked userid. And because the uid revocations are n=
ot=20
displayed when the key is parsed by gnupg, but key revocations are, the
possibility of this misunderstanding occuring is fairly large.
