bug#6450: emacs 23.2; idlwave.el: error in idlwave-action-and-binding function

[Jose Marino]

While using major mode idlwave I get an error every time I press one of 
these keys: ,  >  <  =

For '=' I get:
call-interactively: Symbol's value as variable is void: idlwave-expand-equal

For ',' I get:
call-interactively: Symbol's value as variable is void: idlwave-surround


I located the error in file idlwave.el in function: 
idlwave-action-and-binding.
The following patch (using code from idlwave-6.0) fixes the problem:

 ;; Set action and key bindings.
