Is there another way to figure out how wide the windows that would
result from a horizontal split would be?

And if you want to avoid the problems you mentioned, you could go with:

--8<---------------cut here---------------start------------->8---
(defun th-split-window-function ()
  (if (>= (let ((edges (window-edges)))
            (- (nth 2 edges) (nth 0 edges)))
--8<---------------cut here---------------end--------------->8---

I don't use scroll bars, so if the current window is 162 columns wide a
horizontal split will result in two 80 column wide windows.  Two columns
will be occupied by the additional fringe.

Anyway, I like Juri's suggestion because it gives the user a very good
control over splitting decisions.
