VT100s do insert and delete line by defining a scrolling region on
the screen and either scrolling up or down (example: region 10 to 24;
scroll down results in open line at 10 and lost line at bottom). On
UNIX, termcap (terminal capabilities stuff) can have an entry for
VT100-like scrolling regions (a subset of an ANSI standard) and editors
may choose to use them.

Insert character and delete character can be done with a line rewrite,
which is slow but not too annoying at 1200 baud.
