Arnaldo Carvalho de Melo 0422a4fc2c perf diff: Fix usage array, it must end with a NULL entry
Fixing this:

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

  usage: perf diff [<options>] [old_file] [new_file]
 Segmentation fault
 [acme@doppio 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.
