I believe you have done a great job implementing this, but I do not
think it is finished until the visual movement is implemented too.

I think you are right. And I think that visual movement should be the default.

I am sure they only referred to the (missing) implementation of visual
movement ;-)

And the core part of this implementation is of course already done
when the text is displayed correctly on screen. (Which does not mean
that the rest is necessarily easy to do.)
