According to gpg2's doc/DETAILS:
For each signature only one of the codes GOODSIG, BADSIG,
EXPSIG, EXPKEYSIG, REVKEYSIG or ERRSIG will be emitted.
gpg1 ("classic") behaves the same (although doc/DETAILS differs).
Currently, we parse gpg's status output for GOODSIG, BADSIG and
trust information and translate that into status codes G, B, U, N
for the %G? format specifier.
git-verify-* returns success in the GOODSIG case only. This is
somewhat in disagreement with gpg, which considers the first 5 of
the 6 above as VALIDSIG, but we err on the very safe side.
Introduce additional status codes E, X, Y, R for ERRSIG, EXPSIG,
EXPKEYSIG, and REVKEYSIG so that a user of %G? gets more information
about the absence of a 'G' on first glance.
