No, I propose this as a solution to Juri's problem, instead of his 
proposed solution to "revert the buffer immediately" with C-x x g, which 
is indeed too drastic.  Something even better to take Lars' suggestion (do 
not ask confirmation when the buffer has not been modified) into account:

(defun revert-buffer-short-answer (&optional ignore-auto noconfirm 
preserve-modes)
  (interactive (list (not current-prefix-arg)))
  (let ((use-short-answers t)
        (noconfirm (not (buffer-modified-p))))
    (revert-buffer ignore-auto noconfirm preserve-modes)))
