 is no name in the termcap database that represents
the full 6429 spec, so for those we're stuck with using historical
implementation names like "vt220", "xterm" and "dtterm".

I've chosen "dtterm" as it is the newest, I believe matches the ANSI
spec best and some of it's extra features,
like glyph gutters, are already implemented in Term.
