I have just committed a change that makes the scrollbar arrows work
like those on a spinbutton:

 button-2 - move by pages
 button-3 - move to end

I don't think the suggestion that button-2 should move to the other
end is that intuitive (Some people might think that it should move in
steps in the other direction, and it definitely should act the same as
in the gtkspinbutton.) 

If moving in both directions using the arrows is that common, the
right solution is probably to make the feature overt and use
NeXT-style arrow positioning, not to make it a hidden feature.
(especially since 2-button mice are pretty common) 

Thanks for the suggestion,
