Except that for CTRL-C as interrupt, this doesn't quite work because if 
Octave is busy doing something, readline will not be getting the CTRL-C 
input, so will have no way of triggering the interrupt.  So in that 
case, we either need CTRL-C to generate a signal external to Octave and 
its GUI, or we need some shortcut (could be local to the terminal 
widget) that can be used to generate an interrupt signal when Octave is 
not sitting at the readline prompt.
