On HP-UX, "vi" will read the LINES and COLUMNS env variables, but it
can't react to window changes after it has started.  The reason is
pretty straight-forward -- HP-UX uses the AT&T tty interface, which
doesn't have any way to query for the window size.  The Sun tty driver
does have that information (struct winsize) and also has SIGWINCH, to
notify the application that something has changed.

Just run this after resizing a window, and before starting "vi":

   eval `resize`


That is the best I can offer right now.  I don't like the situation,
either.
