Are the lines below more helpful?


** Changes affecting display-buffer

*** display-buffer tries to be smarter when splitting an existing window.

**** The new option split-window-preferred-function lets you either
choose among a number of standard methods to split the window or provide
your own splitting function.

**** The new function split-window-sensibly which provides the default
value for split-window-preferred-function tries to split a window
horizontally when vertical splitting fails.

**** split-height-threshold and the new option split-width-threshold let
you specify in more detail whether and how split-window-sensibly shall
split the window.

**** A window can be split vertically even when it's not full-width.

*** If pop-up-frames has the value `graphic-only', display-buffer
makes a separate frame on graphic displays only.

*** select-frame and set-frame-selected-window have a new optional
argument NORECORD.  If non-nil, this avoids messing with the order of
recently selected windows and the buffer list and allow to more
correctly identify the window least recently used when displaying a
