pacman-key would exit with an error here, but still show the success
message from gpg itself, e.g. if my key is TRUST_ULTIMATE:
$ pacman-key --verify curl-7.25.0-1-x86_64.pkg.tar.xz.sig
gpg: Signature made Thu 22 Mar 2012 07:51:44 PM EDT using RSA key ID F56C0C53
gpg: NOTE: trustdb not writable
gpg: Good signature from "Dave Reisner <firstname.lastname@example.org>"
gpg: aka "Dave Reisner <email@example.com>"
==> ERROR: The signature identified by curl-7.25.0-1-x86_64.pkg.tar.xz.sig could not be verified.
