Actually, this might not be so crazy. Sometimes you get a signed sha*sums file
instead of signed source, so you don't include the key in validpgpkeys array.
For example, when building Firefox, I have to manually verify the sig on
SHA512SUMS and then paste the sha512sum into PKGBUILD. But this is because I'm
paranoid... I guess one can simply do makepkg -g, hmm.

Hence the question, why have this flag at all? And should it be possible to
specify an external (signed) hash-file in PKGBUILD?
