If by ``wrapped lines'' you mean continuation lines, then (AFAIK) we
still need to walk to the end of a line before we are able to display
it and all the lines after it. If by ``wrapped lines'' you mean
something else, perhaps that belongs to the recent features whose
effect on display engine I didn't yet have time to grasp, so I cannot
answer the question.

[How come you are suddenly in favor of unibyte operations?]
FWIW, I think editing binary files other than via hexl is playing with
fire, anyway. But that's me.
