+ - If --backup is combined with --delete without --backup-dir (and
+ without --delete-excluded), we add a "protect" filter-rule to ensure
+ that files with the backup suffix are not deleted.
+
+ - The file-count stats that are output by --progress were improved to
+ better indicate what the numbers mean. For instance, the output:
+ "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
+ to be transferred, and we still need to check 8383 more files out of
+ a total of 9999.
