Raman, in this thread [1] we are given green light to improve 
command-error-function. Could you provide an example of the operation, 
that would be handled badly by command-error-function? For me it seems 
to be the best solution. For example it delivers "read only" message 
properly.

Further, if "key undefined" was also populated as an error-message, it 
would not require special handling by Emacspeak. This is all a song of 
the future (Emacs 25), but why not having a good plan?

By now you could start using command-error-function as if it was our 
private variable, later it would be made better accessible for packages 
and then we would adjust to new standards.
