I've also had problems with xterms getting auto-wrap turned off.  And,
yes, nvi triggers this problem

For a while I thought this might be an xterm problem -- or even an
ncurses problem.  All of these coordinate to manage the layout of
characters...  However, less, more and emacs -nw don't trigger this
problem, so you're probably right that it's an nvi problem.

As a start, here's the begining and end of an nvi xterm session (as
reported by cat -v):

(B)07[?47h[?7h[?1h=


^[[K^[[24;1H^[7^[[1;24r^[8^[[2J^[[?47l^[8^[[?7l^[[?1l^[>


Aside: it would be nice if there were a program to map from escape
sequences to terminfo capabilities...  It would be even nicer if the
result could be made an html document with references into appropriate
documentation.
