nicm 022b5cf193 When in copy mode with a large scroll offset and the window is resized ...

so that history shrinks, data->oy can exceed screen_hsize causing an
unsigned integer underflow in the py computation. Clamp data->oy in
window_copy_resize and window_copy_cmd_refresh_from_pane before the
subtraction. From futpib at gmail dot com in GitHub issue 4958.
