I had forgotten about use-short-answers, it makes the proposed solution 
even shorter:

(defun revert-buffer-short-answer (&optional args)
  (interactive (list (not current-prefix-arg)))
  (let ((use-short-answers t))
    (revert-buffer args)))

(global-set-key (kbd "C-x x g") 'revert-buffer-short-answer)
