Hi Stefan, sorry about that -- I moved the function to display the buffer
from the beginning to the end and didn't take into account that it also
is responsible for making the buffer current.

Here's the fixed version:

(defun switch-to-new-buffer ()
   "Switch to a new buffer.
The buffer name is the value of `switch-to-new-buffer-name', or \"*scratch*\"
if that is nil.
See `set-buffer-major-mode'."
   (interactive)
   (let ((new-buffer (generate-new-buffer (or switch-to-new-buffer-name
					     "*scratch*"))))
     (set-buffer-major-mode new-buffer)
     (with-current-buffer new-buffer
       ;; Protect against kill-emacs:
       (setq buffer-offer-save t)
       ;; Protect against kill-buffer:
       (add-hook 'kill-buffer-query-functions
		'switch-to-new-buffer-kill-buffer-query-function
		nil
		t)
       )
     ;; Finally, select:
     (switch-to-buffer new-buffer)))
