documentation should be updated too.

Hi Ingo and KOSAKI-san,
Sorry, now this patch conflicts with my patch(commit 1464010) on the
latest -tip tree. The patch drops $argN support, so I updated the
1st example command.
Thank you,

Still you should add your sob, since you are delivering the patch,
Andrew one reminded me on this. Also you can refer to
Documentation/SubmittingPatches:
The Signed-off-by: tag indicates that the signer was involved in the
