command-error-function default handler

[Jarek Czekalski <jarekczek@poczta.onet.pl>]

I was adviced to use command-error-function. However despite my 
selective error handling I want a default error handling to be performed 
too. I look into keyboard.c and see that the main activity of default 
handler is calling print_error_message.

But how do I do that from elisp?

It would be nice if command-error-function documentation explicitly say 
how to install custom error handling so that default handling still 
occured. Or at least how to display the message in most compatible way.

The similar issue is with bell. The docs does not say how to mimic 
default bell.

Thanks
