it's a weird backwards compatibility thing; if you call "get" directly
after you've created the scrollbar, it operates in "pre-Tk 4.0" mode,
and returns four values:

    total, window, first, last

to get normal behaviour, you have to call the "set" method with
two arguments (see the docs).  once you've done this, "get" will
work as documented.

note that if you attach a scrollbar to a scrollable widget, Tk(inter)
will do this for you all by itself.
