[Toybox] [PATCH] vi: fix warnings, improve status display.

[Jarno Mäkipää]

Hi

Yeah I have been about to remove that statusline thingy, it was mostly
to debug some stuff, such as mode switch and cursoring around. This
more classical look is better. In fact I already had similar patch
ready, along with few other fixes, but I have been busy travelling
past few weeks in Taiwan. So didint have time to send them.

I will rebase myself on top of this and send my own fixes after Im
done with travelling next week or so.
