	* gtk/gtkwidget.h:  Add some documenting comments about
	  GTK_CAN_DEFAULT, GTK_HAS_DEFAULT and GTK_RECEIVES_DEFAULT
	  just as owen said on irc.

	* gtk/gtkwindow.c (gtk_window_set_default):  Don't blindly
	  set HAS_DEFAULT.  Only set it if there isn't another window
	  holding it (a focus window which RECEIVES_DEFAULT) and only unset
	  it if the widget is not the focused window with RECEIVES_DEFAULT.
	  This fixes weird double default bugs in dialogs which has things
	  call gtk_window_set_default at times.
