No - as you discovered - that won't work.

Yes, assuming a braille window width of 32 columns, that's the right way to do
it.
>However, this never moved the cursor beyond the first line.
Please apply the attached patch - multiline-routing.patch - and let us know if
it fixes (or doesn't fix) the problem.
