Subject: [PATCH 1/1] perf diff: Fix usage array, it must end with a NULL entry

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Fixing this:

[acme@...pio linux-2.6-tip]$ perf diff --hell
  Error: unknown option `hell'

 usage: perf diff [<options>] [old_file] [new_file]
Segmentation fault
[acme@...pio linux-2.6-tip]$

Also go over the other such arrays to check if they all were OK, they
are, but there were some minor changes to do like making one static and
renaming another to match the command it refers to.
