It's a fair point, but I see the first error as verifying the
checksum file itself, and so separate functionality.

Related to this is outputting "MISSING" as well as "OK"
unless --quiet is specified, though I thought the lack
of "OK" if no files found would be enough indication
of an issue in the normal usage?
