- /* #### This is utterly disgusting, and is probably a remnant from
- legacy code that used `ding'+`message' to signal error instead
- calling `error'. As a result, there is no way to beep from Lisp
- directly, without also invoking this aspect. Maybe we should
- define a `ring-bell' function that simply beeps on the console,
- which `ding' should invoke? --hniksic */
