If the left and right margins are set to the right of the current horizontal
position, the new left and right margins become valid in the same line.
If the left margin is set to the left of the current horizontal position and the
right margin to the right of the current horizontal position, the right
margin becomes valid in the same line, but the left margin setting becomes
valid in the next line.
When the left and right margins are set to the left of the current horizontal
position, both left and right margin settings appear to become valid in the
next line. This is because an AUTO CR is performed by the following data.
