    dirdiff: Fix old, old regression in initial cursor position
    
    No idea when this broke, but because we just set the selection instead
    of setting the cursor position, when you start up a folder comparison
    you couldn't immediately navigate with Alt+Up/Down; you needed a cursor
    move first.
    
    There's no good reason for this, so just fix it up by setting the cursor
    on initial load instead.
