-;; The variable `help-window' below is used by `help-mode-finish' to
-;; communicate the window displaying help (the "help window") to the
-;; macro `with-help-window'. The latter sets `help-window' to t before
-;; invoking `with-output-to-temp-buffer'. If and only if `help-window'
-;; is eq to t, `help-mode-finish' (called by `temp-buffer-setup-hook')
-;; sets `help-window' to the window selected by `display-buffer'.
-;; Exiting `with-help-window' and calling `help-print-return-message'
-;; reset `help-window' to nil.
