Yes, as I said, it doesn't solve the performance problem.
Still, it doesn't complicate the code, and it significantly
improves speed in code likely to be executed often, so it
seems worth doing in its own right.

If we ever need that ability we can put it back in. In the meantime
there's no need for the generality and I found it confusing.

Sure, what name do you suggest? scan_newline is already taken.
Perhaps scan_buffer_newline?
This area is a bit messed up, unfortunately -- scan_newline has
comments saying that it looks for carriage return (!) but
it does not in fact do that.
