Well, automation can turn it off via --no-big-num, right?

Also, i think for automation we'd also like to have a 'simple output' mode, 
would you like to add that?

Something a bit like what you can see in 'perf stat -v true':

 $ perf stat -v --no-big-num true
 task-clock: 164545 164545 164545
 context-switches: 0 164545 164545
 CPU-migrations: 0 164545 164545
 page-faults: 83 164545 164545
 cycles: 518743 169550 169550
 stalled-cycles-frontend: 326178 169550 169550
 stalled-cycles-backend: 269753 169550 169550
 instructions: 326864 169550 169550
 branches: 67886 169550 169550
 branch-misses: 3874 169550 169550

Without the human output later on, and with elapsed time added as well.

Thanks,

	Ingo
