Correct. I meant "SHOULD" return an intermediate (213) reply for long-running...

Right. I was only suggesting a "213-" response line, which isn't the final 
line of a 213 so I don't think we'd have to write anything in particular to 
allow a server to do that. It would be following standard FTP behavior.

We could of course still add something in the spec to make it more obvious 
that this might be a good idea for servers to do.
