It isn't. My terminal is a VT100 (made by DEC - or, if it isn't, I can get the manufacturer into a hell of a lot of trademark trouble) and it has no such feature. It exists on some VT100-family terminals from DEC (but not the VT100), it probably exists on some VT100-compatible terminals, and it exists on VT100s with the printer port option. I suspect your EDT knows that it's not running on a vanilla VT100. There is an "edit mode" flag, settable with the SET TERMINAL command and gettable, at least, with some QIO function, which says that the terminal supports the ANSI standard insert/delete line/character functions. It probably looks at that. Either your VT100s are non-standard and it is sending those sequences, or they are standard, that flag isn't set, and EDT sees that fact and doesn't use insert/delete line.
