bug#8936: 24.0.50; Incompatible change in the meaning of "other window"

[Bob Rogers]

   The problem is that C-x 4 b now creates a new frame to display the
buffer, instead of creating or reusing a window in the current frame.
This can be reproduced by typing "C-x 4 b" as the first thing in a fresh
"emacs -Q"; you will see the *Messages* buffer opened in a new frame.

   This is in emacs trunk via git last updated today at 21:59:08 UTC.
