Since we already have the commands to split the current window,
shouldn't we also have the commands to split the current frame:

```
diff --git a/lisp/window.el b/lisp/window.el

--- a/lisp/window.el

I don't think I understand what this is supposed to do.  When testing
it, it just splits the topmost window (no matter what window is
selected), and I don't undertand why anybody would want that in
particular.

If the window configuration is like the following,

and may be you would like to add aliases, just like

split-window-horizontally -> split-window-right,
split-window-vertically -> split-window-below

The word "below" is not quite correct because
display-buffer-below-selected uses positioning
relative to the current window.  Whereas the
corresponding function the uses the absolute
positioning contains the word "bottom" in its name:
display-buffer-at-bottom.

So the right alias would be split-frame-at-bottom.

Also display-buffer-in-direction supports the word
"rightmost", so its counterpart alias would be
split-frame-at-rightmost.

Then why not add also split-frame-at-leftmost
and split-frame-at-top?

Oh, I see.  Yes, then I think Juri's new commands look useful.

I applied the patch series from bug#56791 instead, since they do the
same.
