I'm using an xterm, but my example should work for all ANSI x3.64
compatible terminals.

A, well then I guess on some versions of NetBSD, including what you're
using, the console is not ANSI x3.64 compatible.

I'm not sure what you're complaining about then.  No matter how you
manipulate the characters on the screen, the behaviour of a horizonally
scrolling line editor is going to be essentially exactly the same.  The
way pdksh manipulates the terminal happens to be quite portable across
terminals and hosts.

I've never encountered a system where zsh might be the only POSIX-like
shell available to me, so I've never bothered to test it.  However that
fragment above will not "fail" with zsh -- it just might not do
everything you want, which is why I suggested that you look at the
complete implemenation in my archive.

You should look again when you've had more sleep!  :-)
