I use this code but one can certainly do better:
8<------8<------8<------8<------8<------8<------8<------8<------8<------
(defun pi-?comment ()
  (interactive)
  (save-excursion
    (if mark-active
        (let ((br (region-beginning))
              (be (region-end)))
          (comment-or-uncomment-region br be)
          (indent-region br be))
      (let ((br (progn  (back-to-indentation) (point)))
            (be (progn (end-of-line) (point))))
        (comment-or-uncomment-region br be)
        (indent-according-to-mode)))))
(global-set-key (kbd "C-%") 'pi-?comment)
8<------8<------8<------8<------8<------8<------8<------8<------8<------
