[pacman-dev] [PATCH 2/3] makepkg: show full fingerprint on pgp failure

[Dave Reisner]

Rather than implementing suffix matching, which might clash, let's just
print the full fingerprint of the err'ing key so that the user can
copy/paste it into validpgpkeys. Also, make it clear in the manpage
that validpgpkeys needs full fingerprints, and nothing else.
