Make groups visible in output:

Before:

{cycles,instructions} ->
cpu_atom/cycles/,cpu_atom/instructions/,cpu_core/cycles/,cpu_core/instructions/

After:

{cycles,instructions} ->
{cpu_atom/cycles/,cpu_atom/instructions/},{cpu_core/cycles/,cpu_core/instructions/}

Committer testing:

Before:

  root@number:~# perf record -e '{cycles,instructions,cache-misses}' /tmp/bla
  Failed to collect 'cycles,instructions,cache-misses' for the '/tmp/bla' workload: Permission denied
  root@number:~#

After:

  root@number:~# perf record -e '{cycles,instructions,cache-misses}' /tmp/bla
