I'm using this:

(defun srb-quit-help (&optional any-frame)
  "Quit *Help* buffer without selecting it.
With prefix argument ANY-FRAME quit *Help* on any visible frame,
otherwise quit *Help* buffer only on the selected frame."
  (interactive "P")
  (let ((help-window (get-buffer-window "*Help*" (if any-frame 'visible))))
    (when help-window
      (with-selected-window help-window (quit-window)))))
(global-set-key "\C-cq" 'srb-quit-help)

Of course, if such a command were added to Emacs, it would need a key
binding not reserved for users, and that's where the real difficulty
lies.
