[meld] Remove unused change range arguments and cleanup appropriately

[Kai Willadsen <kaiw src gnome org>]

commit 686aac8799d0c54cac3f512b40d54f9bcbc5d1fe
Author: Kai Willadsen <kai willadsen gmail com>

    Remove unused change range arguments and cleanup appropriately
    
    FileDiff._update_highlighting() has unused arguments, making the return
    values for Differ.change_sequence() and Differ._change_sequence() also
    unused. This commit removes all of these, plus the unused
    all_changes_in_range() method from Differ.
