    libide: add IdeSourceView::append-to-count gsignalaction
    
    This will let us pass numbers from keybindings to do multiple replay
    operations. 10dw for example. This will be 1 pushed followed by 0
    pushed. Then the `dw` operation will use a movement of w (inclusive)
    and repeated 10 times before the `d` is applied.
