*
* Number of bytes that are _not_ copied from the source is deletion,
* and number of inserted literal bytes are addition, so sum of them
* is the extent of damage. xdelta can express an edit that copies
* data inside of the destination which originally came from the
* source. We do not count that in the following routine, so we are
* undercounting the source material that remains in the final output
* that way.
* is the extent of damage.
