Hello all, Could the %G? format differentiate between an unsigned commit and a signed commit that you're missing a public key for? If `git show --format=%GG --no-patch <commit>' produces an output like the following: gpg: Signature made <date> using RSA key ID <id> gpg: Can't check signature: public key not found Then currently %G? results in `N', the same as an unsigned commit. In this case, could %G? please result in a new character? Perhaps `M' for "missing public key"?
