Thank you, God!

```
New commands 'split-root-window-below' and 'split-root-window-right'.
These commands split the root window in two, and are bound to 'C-x w 2'
and 'C-x w 3', respectively. A number of other useful window-related
commands are now available with key sequences that start with the
'C-x w' prefix.
