json.Decoder.Decode returns after one value, so `--values '[[1]] trailing'`
was accepted as a valid matrix and the document got created anyway. A paste
that ran long, leftover shell concatenation, or two JSON values glued

never asked for — and creation cannot be rolled back atomically. Require
EOF after the first value on both flags, following decodeOARequest.
