Interesting vi bug/feature

[Mark Horton]

> Vi is just impossible with the next generation of intelligent terminal.

I don't follow this reasoning at all.  vi works fine on a Sun, on a 5620,
and on any reasonable intelligent terminal or workstation.  Intelligence
normally includes the ability to handle a few escape sequences.  I've
also used vi with a mouse, without modifying vi.

If your workstation is incapable of emulating a terminal, you will be
unable to log in over your network to another host, and unable to use
the rapidly growing library of screen oriented software.  Such a
workstation may make an interesting research tool, but without a reasonable
amount of upward compatibility, it won't sell.  After all, terminals sold
today are upward compatible with the model 33 Teletype.
