Assuming that the variable `split-window-preferred-function' is set to
`split-window-sensibly', you can play with some of the settings mentioned
in the functions's documentation:

| split-window-sensibly is a compiled Lisp function in `window.el'.
| (split-window-sensibly WINDOW)
| Split WINDOW in a way suitable for `display-buffer'.
| If `split-height-threshold' specifies an integer, WINDOW is at
| least `split-height-threshold' lines tall and can be split
| vertically, split WINDOW into two windows one above the other and
| return the lower window.  Otherwise, if `split-width-threshold'
| specifies an integer, WINDOW is at least `split-width-threshold'
| columns wide and can be split horizontally, split WINDOW into two
| windows side by side and return the window on the right.  If this
| can't be done either and WINDOW is the only window on its frame,
| try to split WINDOW vertically disregarding any value specified
| by `split-height-threshold'.  If that succeeds, return the lower
| window.  Return nil otherwise.
| By default `display-buffer' routines call this function to split
| the largest or least recently used window.  To change the default
| customize the option `split-window-preferred-function'.
| You can enforce this function to not split WINDOW horizontally,
| by setting (or binding) the variable `split-width-threshold' to
| nil.  If, in addition, you set `split-height-threshold' to zero,
| chances increase that this function does split WINDOW vertically.
| In order to not split WINDOW vertically, set (or bind) the
| variable `split-height-threshold' to nil.  Additionally, you can
| set `split-width-threshold' to zero to make a horizontal split
| more likely to occur.
| Have a look at the function `window-splittable-p' if you want to
| know how `split-window-sensibly' determines whether WINDOW can be
| split.

I haven't checked whether/how you can restore emacs-22 behavior though.
