dsync prints out "Completed sync" even if you only did 'dsync --help'

In my opinion, there should not be a printout of Completed sync when you do dsync --help. No syncing took place.

$ dsync --help

Usage: dsync [options] source target

Options:
      --dryrun            - show differences, but do not synchronize files
  -b  --batch-files <N>   - batch files into groups of N during copy
      --bufsize <SIZE>    - IO buffer size in bytes (default 4MB)
      --chunksize <SIZE>  - minimum work size per task in bytes (default 4MB)
  -X, --xattrs <OPT>      - copy xattrs (none, all, non-lustre, libattr)
  -c, --contents          - read and compare file contents rather than compare size and mtime
  -D, --delete            - delete extraneous files from target
  -L, --dereference       - copy original files instead of links
  -P, --no-dereference    - don't follow links in source
  -s, --direct            - open files with O_DIRECT
      --open-noatime      - open files with O_NOATIME
      --link-dest <DIR>   - hardlink to files in DIR when unchanged
  -S, --sparse            - create sparse files when possible
      --progress <N>      - print progress every N seconds
  -v, --verbose           - verbose output
  -q, --quiet             - quiet output
  -h, --help              - print usage

[2026-02-05T22:18:41] Completed sync

Start at the dsync command entry point and trace how --help exits and where the "Completed sync" message is emitted. Confirm that help displays usage without performing a sync, then verify the message is absent for dsync --help while remaining available after an actual sync.
