Add more standard sequences.

CSI Pn b (Repeat previous char)
	Actually mildly useful... repeat any character.
CSI Ps d (Line position absolute)
	Moves to a specific row without changing column.
	Mildly useful.
CSI Pn a (Cursor forward)
	Identical to CSI Pn C
CSI Pn ` (Absolute position in line)
	Identical to CSI Pn G
ESC H (Add Tab Stop)
	ie: Break everything else that uses tabs this session.
CSI Pn g (Clear Tabs)
	ie: Break everything else that uses tabs this session.
CSI 2 $ w (Request Tab Report)
	So, maybe it can be fixed after you break it!  Yay!
ESC M (Reverse Line Feed)
	Basically up one line.  Not really useful since we have cursor up.
CSI Ps e (Line position relative)
	Identical to CSI Pn B
