Add output of rsync --stats or --info=stats[1-3] * FEATURE REQUEST

[tristangrimaux]

rsync outputs extra info when called with the argument --stats or --info=stats[1-3]. This is very useful to make a dry-run and check how big the transfer will be.

It's different from the summary as it lists the amount of bytes transferred and in the case of of a dry-run it is just the names of the files.,

In this example a dry run gives 1.29M of data transferred vs the 759.17G bytes that are the Total transferred file size reported in the stats portion.

sent 8.99K bytes  received 1.29M bytes  370.21K bytes/sec
total size is 6.88T  speedup is 5,311,650.06 (DRY RUN)
