to see this bug, you also need the 'c' & 'w' options, and output that is
more than one screen long. for example:

[tatooine:/usr/src/contrib/less:ttyp4] less -ecw scrsize.c

(hit space until you reach the last page, then one more time)

less exits leaving your cursor near the top of screen in the middle of
the text that was displayed there, and does not correctly restore the
terminal settings:

                 return 1;
[tatooine:/usr/src/contrib/less:ttyp4]
                 return 1;
         if (!(hints.flags & PResizeInc))
                 return 1;
         if (hints.width_inc == 0 || hints.height_inc == 0)
                 return 1;
         if (!(hints.flags & (PBaseSize|PMinSize)))
                 return 1;
         if (hints.flags & PBaseSize)
