Thank you!  I just Googled the variable you pointed me to 
(split-width-threshold), and instantly turned up the Emacs 23.3 page at 
http://www.gnu.org/software/emacs/elisp/html_node/Choosing-Window.html, 
which describes the function display-buffer. display-buffer is described 
as "the basic facility that chooses a window to display a buffer in."  
This sounds like exactly the function I was looking for.  The 
documentation shown when I run M-x describe-function display-buffer in 
21.3 doesn't contain any mention of a variable named 
split-width-threshold, which is pretty strong evidence that that feature 
wasn't added until some later version.
