That seems quite absurd, TBH. I know we've catered for some absurdity in 
the CSV code (much of it down to me), so maybe we need to be liberal in 
what we accept here too. IMNSHO, we should produce either a single JSON 
document (the ARRAY case) or a series of JSON documents, one per row 
(the LINES case).
