If you know the size of the small gap between the frame's right border
and the right edge of your display (say, 3 pixels), then you could do
this:

        (set-frame-position frame -1 ypos)
        (set-frame-position frame (+ 3 (frame-parameter frame 'left)) ypos)

This may be caused by the way that function x_calc_absolute_position()
converts negative left and top frame offsets into equivalent positive
offsets for your windowing system.
