Hmmm, sounds a bit odd. The way GtkContainer's ->focus() method
works is that:

 - if CAN_FOCUS is set, then the widget itself is focusable  
   but not it's children.

 - if CAN_FOCUS is not set, then the widget's children are
   focused but not the widget itself.

I'd really expect GtkPaned to override ->focus() itself
rather than setting this flag; Toggling this flag on
the fly was never intended to be done normally.
