amount columns. The contents of the
amount right-most columns in the scroll region are lost.

All other cleared space is colored according to the current SGR state.
amount = 0 it's adjusted to 1.
The Cursor position is not changed.
🛆 As of xterm 346 split multi column cells are erased using the current SGR state instead of keeping the background color.
