even-window-heights

[Chong Yidong]

This variable's docstring says:

  If non-nil `display-buffer' will try to even window heights.
  Otherwise `display-buffer' will leave the window configuration alone.
  Heights are evened only when `display-buffer' chooses a window that
  appears above or below the selected window.

And the manual says something similar.  But in fact the windows are
evened only if the new window is shorter than the selected window.

This has been the case since

Martin, do you remember why you made this change?
