>
> {{NodeDocument.getVisibleChanges()}} ensures visible changes are returned in
> descending revision order. In some cases this requires merge sorting of
> changes from different previous documents. The current implementation tries
> to avoid the merge sort by looking at the ranges of the previous documents
> and switches to a merge sort if they overlap. The implementation should be
> further optimized to only merge sort the subset of ranges that overlap and
> not the entire set of referenced previous document.
