From my experience with cmdtool (on both XView and SunView), its always
been like that.  I guess that's why when it's started under the name
`shelltool' the scrollbars are disabled.

I made an attempt at getting this stuff to work under (BSD 4.2 derived)
Ultrix 3.1 -- and had similar problems caused by the lack of some of
those ioctls.
