split: use a sensible default width

Guessing a width/height with v?split is rather bothersome, using a
sensible value based on the user's terminal would be preferable. This
also prevents confusion when running :v?split without a number seemingly
does not open a split.

Initialize width as half the width of the message list and height as an
eight of the message list.
