Adapted this as suggested for the new version of the patches, opted 
however for splitting it into 2 lines:
- number of processed and unmodified files
- reused data, padding and total, as well as number of reused chunks and 
partial chunks

This output is now only shown when there is a payload writer available 
and the second line is not shown if there was no reused data.
