It's not clear what you mean, whether you're talking about only a daemon,
or a client message or what.  If you have transfer logging enabled in a
daemon, only non-dry-run files will be logged as transfers.  If you're
talking about a client, you can always use --info=stats (or --stats on an
older rsync) to see the trailing stats lines that mentions "(DRY RUN)".

If you end up parsing args in a pre-xfer script, be sure to weed out any
arg-specifying short options from your checking for the -n arg (e.g.
/^-[^BefMT]*n/) and some non-official passing of the long (--dry-run)
option as well.
