I noticed a small inconsistency in delete and insert line between xterm and libteken. libteken allows these actions to happen while the cursor is placed outside the scrolling region, while xterm does not. This behaviour seems to be VT100-like. Confirmation: http://www.vt100.net/docs/vt102-ug/chapter5.html "This sequence is ignored when cursor is outside scrolling region." MFC after: 1 month
