I lifted this restriction in revision 110885 on the Emacs-24 release
branch.

As a matter of fact, the code called that function with the variable
`display-buffer-alist' as second argument which doesn't make any sense.
I now pass it the ACTION argument of `display-buffer' instead and tried
to document this in the same revision as above.

Thanks, martin
