In Emacs 22 `display-buffer' tries to split the largest window first
and, if that fails, the least recently used window.  This behavior is
unchanged in Emacs 23.

In Emacs 22 `display-buffer' didn't try to split the largest window
vertically when it was not full-width.  No such restrictions applied for
the least recently used window.  In Emacs 23 the largest window can get
split even when it's not full-width.

To get the old behavior back in your case it will be best to write your
own `split-window-preferred-function' just as we're currently trying to
do for `dired-pop-to-buffer'.  This will let you specify explicitly
which window `display-buffer' should try to split and whether it should
split it vertically or horizontally.
