I intended to leave the behavior as close to Emacs 23 as possible,
(e.g. calling M-x display-buffer on *shell* would bring up *shell* in
the same window), but you are correct: the old behavior does not make
sense, so we might as well change it.

I've now changed all those callers to use switch-to-buffer and/or
switch-to-buffer-other-window.

No, it should be non-nil.  Otherwise, someone who wants to customize it
would have no working initial template.  Anyway, we might improve the
Customize interface for modifying alists.
