This is by intention.  Applications that used `display-buffer-function'
before Emacs 24 wouldn't know how to handle these arguments.

Add to `display-buffer-alist' a regexp matching the names of the buffer
you want to handle via your `display-buffer-function' plus the function
of your choice.  Don't use `display-buffer-function', it's here for
compatibility with earlier Emacs versions only.  Check with the code of
`display-buffer' to know what will be passed to your function via the
ALIST argument.
