--info=mount now prints rsync's mount-point skip line (matching rsync
3.4.1, which emits it for repeated -xx and drops the mount-point dir);
--info=stats enables the same block as --stats; -x is repeatable.
--stats counts traversed directories for the Number of files breakdown
even when no directory metadata is captured (-r without -t/-p).
--debug enables real output for flist/del/hash/deltasum/recv/filter/send
at their natural FastSync events (synthetic categories stay inert).
--stats and --debug rows keep their documented residual status.
