I'm trying to use your implementation of display-buffer-in-direction,
but with this patch:

diff --git a/lisp/files.el b/lisp/files.el

 			       (if offer-save "y, n, or !" "y or n")

while visiting a file with Local Variables it fails with:

Debugger entered--Lisp error: (error "Cannot share edge from within live window #<window...")
  signal(error ("Cannot share edge from within live window #<window..."))
  error("Cannot share edge from within live window %s" #<window 6 on etc>)

  display-buffer(#<buffer *Local Variables*> (display-buffer-in-direction (direction bottom main)))
  pop-to-buffer(#<buffer *Local Variables*> (display-buffer-in-direction (direction bottom main)))

Please help.
