I rename it in the source array:
That way makepkg doesn't think it's a PGP signature. Note that the
SHA256.sig file has the checksums embedded in the file, as the
signature/additional comments are at the top and take up at most two

Signify verifies the signature and then verifies the checksums of each
file. While I could just use the sha256sums array, I prefer using
signify as that is how the OpenBSD project distributes their files
securely. Since these files can also be downloaded in the clear (FTP),
verifying them becomes an absolute must.

I'm not sure what the problem is here, isn't validating the signature
and checksums not good enough?
