(defun current-minor-modes (&optional buffer)
  "The list of the minor modes currently active in the buffer (or current 
buffer)."
  (let ((result '()))
    (with-current-buffer (or buffer (current-buffer))
      (dolist (mode minor-mode-list result)
        (when (and (boundp mode) (symbol-value mode))
          (push mode result))))))
