I meant `even-window-heights'. I use an even-window-sizes specifier
because it applies to the horizontal case as well.

It would have permitted to deduce in which case the window-pub branch
failed to mimic the behavior of the trunk.

Yes.

`split-window' can split an arbitrary window. My
`display-buffer-regexps', for example, contains the entry
(("ChangeLog.*")
same-frame
(reuse-buffer-window)
(new-window
(root . below))
(min-height . 6)
(min-width . 60)
(adjust-height . 8))
so I can run ediff in side-by-side windows and edit a ChangeLog within
one and the same frame without disrupting the ediff setup.
Or, you can make sure that your completions always appear in a window on
the right of the frame by adding something like
(("*Completions*")
same-frame
(reuse-buffer-window)
(new-window
(root . right)))
to `display-buffer-names'. And, since I'm able to display a buffer on
an arbitrary side of a window I can write
(("*Choices*")
same-frame
(reuse-buffer-window)
(new-window
(selected . above)))
and have ispell use `display-buffer' for the *Choices* buffer. This
means that people who want to see the *Choices* buffer on a separate
frame can do so by simply customizing `display-buffer-names'.
