Bug found in ui.c.

I found a bug in the region calculate function in ui.c.

region region_calculate(region loc)
{
        int w, h;
        Term_get_size(&w, &h);

        if (loc.col < 0)
                loc.col += w;
        if (loc.row < 0)
                loc.row += w;
        if (loc.width <= 0)
                loc.width += w - loc.col;
        if (loc.page_rows <= 0)
                loc.page_rows += h - loc.row;

        return loc;
}

As you can see the action following the second if statement is incorrect. It should be:

        if (loc.row < 0)
                loc.row += h;

That is add h(eight) not w(idth) to row.

Fixed- thanks.
