There wasn't much of a reason to leave a loop early on 0x0d or null. The idea was that once you have a CR or null, the rest is garbage and you shouldn't see it. However, it brought a problem: In VE, you couldn't insert characters past that limit. It would be written, but never displayed. So let's get rid of this logic and simply always display a 64x16 grid.
