I think what Per was looking for was more something along the lines of

(defun edit-read-only-file-maybe ()
  (when (y-or-n-p "file is read-only, raise privileges to edit? ")
    (find-alternate-file
     (format "/sudo::%s" buffer-file-name))))

(add-hook 'first-edit-read-only-file-hook 'edit-read-only-file-maybe)

with the main problem being that `first-edit-read-only-file-hook'
doesn't exist, and there don't seem to be any analogs. Or at least I
can't find them.
