OK. That's what I've done now (code is in the keyring_editor_can_sign
function in keyring.c). I noticed, though that the self signature of the
key is apparently not present in the list of signatures I get with
gpapa_public_key_get_signatures. Is that by design or is it an
implementation detail. I'm a bit surprised by this, because gpg
--list-sigs lists the self signature just like the other signatures.

The main reason I asked, though, is that I'm somewhat concerned about
efficiency. This code will have to be run everytime the selection may
have changed, which basically means for every mouse click in the list of
keys.
