    brlapi: Fix backspace synthesis in xbrlapi
    
    Even if the alternate code without retaindot is the same as the code
    with retaindot, we need to call whoGetsKey. Otherwise xbrlapi does not
    get backspace keycodes: they produce the same keycode with/without
    retaindot, but since xbrlapi sets retaindot to 0, it would not get them
    from the first call.
