Subject: Add key-binding targets to PGPPacket._parse_signature_packet
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1664f3b4ed402b51187191215233d8d5900f9a85;p=gpg-migrate.git

Add key-binding targets to PGPPacket._parse_signature_packet

Also adjust the 'user id and public-key packet' targets to always grab
the first packet in the list (public or private) instead of always
looking in the public packets.

This commit assumes that we're loading public packets first, and if a
key has any secret packets, then the current packet is a new secret
packet.
