So the suggested change is:

diff --git a/lisp/net/rcirc.el b/lisp/net/rcirc.el
index 0d30b34922..815dfef50f 100644
--- a/lisp/net/rcirc.el
+++ b/lisp/net/rcirc.el

       (with-current-buffer chat-buffer
 	(rcirc-print process sender "NICK" old-nick new-nick)
 	(setq rcirc-target new-nick)
-	(rename-buffer (rcirc-generate-new-buffer-name process new-nick)))
+	(rename-buffer (rcirc-generate-new-buffer-name process new-nick) t))
       (setf rcirc-buffer-alist
             (cons (cons new-nick chat-buffer)
                   (delq (assoc-string old-nick rcirc-buffer-alist t)

Skimming the code, it seems like this should do the trick (but I haven't
tested it).  Ken, Philip, does this look OK to you?
