csi: check for private marker in 'S' case
The handler for 'S' final character does not check for a private marker. This can cause a conflict with a sequence called 'XTSMGRAPHICS' which also has an 'S' final character, but uses the private marker '?'. Without checking for a private marker, st will perform a scroll up operation when XTSMGRAPHICS is seen, which can cause unexpected display artifacts.
