Scanning for ... isn't even required; it's easier than that. You load the results into a temporary. If you hit a ..., everything prior is premessage and everything after is ordinary. If you never hit a ..., everything is ordinary. So this remains quite trivial to implement even when streaming byte by byte, without having to even scan out. In otherbwords, I agree with you.
