Note my patch has nothing to do with the man page, its already up2date.

I usually dont read the Fine manuals, do you ?

Try :

iptables -t nat -A PREROUTING -p tcp --dport 1234 -j REDIRECT --help

REDIRECT target options:
 --to-ports <port>[-<port>]
				Port (range) to map to.


You see [--random] is missing.
