That was the idea. Each arg_parser gets (what's left of) the current line,
and if they need more data, they'll have to arrange for reading it.
(Otherwise the easy fix would have been to have lineReceived() read
literals as well. I tried this approach first, but I didn't like it.)

That's a thought. I'll keep it in mind.
