>Description:

        resizing an xterm with a vi running in it doesn't work properly.
        vi definately notices, but i think it fails to reset the scroll
        regions.  it is unable to display anything in the new larger space,
        and i believe i see it scrolling ~'s up the screen when the resize
        actually happens.

        i'm pretty sure this started happening with terminfo support.

>How-To-Repeat:

        resize a window with vi.
