Info: Console Vs GUI difference?

[T.V. Raman]

Hi Stefan,

My last attempt at using command-error-function -- appended below
-- only produces a "back to top level"  message in all instances.

Once I can get this working, I'll make the advice on signal
conditional on older emacsuns --
(defun emacspeak-error-handler  (data  context  calling-function)
  "Emacspeak custom error handling function."
               (dtk-speak
     (format "%s %s"
             (or context "")
             (or
              (get (car data) 'error-message)
              ""))))

(declaim (special command-error-function))
                                            (add-function :before
command-error-function 'emacspeak-error-handler)
