    _______________________________________________________

Details:

If I try to use quit as a callback function, an error is given:
----------------------
function myfun
  figure(1)
  set(1,'windowbuttondownfcn','quit')
end
------------------------

If you run the function myfun and click into the figure window, the following
output is given.
-------------
octave:5> myfun
octave:6> error: quit: invalid number of output arguments

octave:6> 
---------------

This does not happen for other functions e.g. grid.
