Subject: tag: recognize rfc1991 signatures
X-Git-Tag: v1.7.3.4~18^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3d5854e765dedfaf2a942e8fa1e950a40f9dcee3;p=git.git

tag: recognize rfc1991 signatures

We have always been creating rfc1991 signatures for users with "rfc1991"
in their gpg config but failed to recognize them (tag -l -n largenumber)
and verify them (tag -v, verify-tag).

Make good use of the refactored signature detection and let us recognize
and verify those signatures also.
