rsync - Jun 2009 - -C flag with --delete-excluded

Can someone tell me if the -C (cvs related) flag would get ignored in
this command:
  /usr/bin/rsync      -aCvv --stats
  --exclude-from=/usr/local/common/baseX/zfs/bin/zfs-exclude.txt
  --delete-excluded
  /cvsbX/zfs/ /usr/local/common/baseX/zfs/

There is no cvs related stuff in zfs-exclude.txt
