Auto-importing missing signatures
Sometimes installing an AUR package will fail with:
[PACKAGE] ... FAILED (unknown public key [KEY]) ==> ERROR: One or more PGP signatures could not be verified!
What just requires the following command to fix it, in case the key isn't fake:
gpg --recv-key [KEY]
It would be nice if that was done automatically.
