[Gtk-sharp-list] Scrollbar.MoveSlider

[Scott Ellington]

On a related note, the docs for Adjustment.Value say this:

"If you set this property, you should manually call
Adjustment.ValueChange so that all listening objects are notified of the
change."

When in fact, the event does get called if this property is changed
manually.  It would be nice if it didn't because then I wouldn't have to
worry about tracking this information.

Would it be possible to change this?
