Of course not, it's in the next patch.

But I was not putting the cumbersome long command line into this
example.

If you really feel strongly about it I guess the two patches could be merged,
but seems cleaner separated.

What kind of example? Full output for a command?

I don't think any other option has that in the man page. It would be
unique.

Having a illustrated `perf tutorial' with examples would probably be a 
good idea, but I'm not sure the man page is the right place for that.
