I'm sure I'm not remembering incorrectly because I still have both
installations. I recently installed Ubuntu in a separate partition
on my laptop. Emacs 21.3.1 runs when I boot Windows XP, and Emacs
23.2.1 runs when I boot Ubuntu. The behavior differences I'm
describing should all be implemented in Lisp, and should therefore
not depend in any way on the OS under which Emacs is running.
working with Emacs 23 or you remember incorrectly.
I just tested this with Emacs 21.4.1.
I did discover something more about 23.2.1's behavior after I
posted. It seems the behavior depends on the width of the top-level
window (what Emacs calls a "frame"). If I have two
vertically-stacked Emacs windows in a small Emacs frame and type C-x
C-b, *Buffer List* is displayed in the other pre-existing Emacs
window. But if I have the same two vertically-stacked Emacs windows
in a large Emacs frame (I frequently work with one Emacs frame
maximized) when I type C-x C-b, instead of displaying *Buffer List*
in the other pre-existing Emacs window, it behaves as if I'd run M-x
split-window-horizontally before running M-x list-buffers.
Just to be sure, I double-checked 21.3.1's behavior (i.e. the old
version), and it doesn't do this. Unless it's starting with only
one Emacs window and has no choice but to split it into two, it
always reuses a pre-existing Emacs window.
So, there can be no doubt that somebody added a new feature that
makes this window-splitting behavior dependent on the width of the
frame, which it never used to be. I'd really like to turn this
