[BUG] perf list: --help option not implemented

From: Stephane Eranian

When I run perf list, I see:

$ perf list
rNNN [Raw hardware
event descriptor]
cpu/t1=v1[,t2=v2,t3 ...]/modifier [Raw hardware
event descriptor]
(see 'perf list --help' on how to encode it)

$ perf list --help

Shows nothing. Looked at the code and I don't see where you handle the --help
option. You need some help to figure out what the modifiers are.

Am I missing something here?
