Yeah, I like to protect *scratch*, too. I have this in my .emacs
to make Emacs query before killing *scratch*:
(defun jh-setup-scratch ()
(with-current-buffer "*scratch*"
(setq buffer-offer-save t)
(make-local-variable 'kill-buffer-query-functions)
(setq kill-buffer-query-functions
(list (lambda ()
(if (buffer-modified-p)
(y-or-n-p "Really kill buffer? ")
t))))))
(add-hook 'emacs-startup-hook 'jh-setup-scratch)
Change `y-or-n-p' to `yes-or-no-p' if you'd prefer to answer
"yes"/"no".
