Actually, what I was saying is that we should have one for the hash
algorithm that is used in the Git object.  I don't care about the hash
algorithm used in OpenPGP, X.509, or OpenSSH (that is, whether it's
signed with SHA-512 or SHA-256), but we can have multiple signatures in
a single commit such that there's both a SHA-1 signature and a SHA-256
signature.
