Just to clarify - the given sample VCDIFF files are forward deltas in 
incremental order, and merge command preserves this order.

Note to developer: this issue happens because of recursion in 
xd3_merge_source_copy. The code already has comments that this logic needs to 
be re-worked because of inefficiency.
