Patch 5.4o.6
Problem:    GTK version generated scrollbar events when setting a scrollbar to
            a specific position.  This can make scrolling happen at the wrong
            moment.  Example: When there is a horizontal scrollbar, 'nowrap' 
            is set and using <BS> in Insert mode to join a line to the 
            previous one.  (Dalecki)
Solution:   Don't pass on scrollbar events when setting the scrollbar
            ourselves.
