Emacs 23.X does this automatically if the current display width is
larger than a customizable threshold:

,---[ C-h v split-width-threshold RET ]--------------------------------
| split-width-threshold is a variable defined in `window.el'.
| Its value is 160
|
| Documentation:
| Minimum width of window to be split horizontally.
| If the value is a number, `display-buffer' can split a window
| only if it has at least as many columns.  If the value is nil,
| `display-buffer' cannot split a window horizontally.
|
| You can customize this variable.
|
| This variable was introduced, or its default value was changed, in
| version 23.1 of Emacs.
`-----------------------------------------------------------------------

Unfortunately, I don't have an Emacs 22.X installation handy today, so
it may be worth checking if your version of Emacs includes this option.
