Applied, with this:

Before:

  $ perf report --stdio -q
    42.77%  ls       ls                [.] _init
    13.21%  ls       ld-2.24.so        [.] match_symbol
    12.55%  ls       libc-2.24.so      [.] __strcoll_l
    11.94%  ls       libc-2.24.so      [.] _init


  #
  # (Tip: Show current config key-value pairs: perf config --list)
  #
  $

After:

  $ perf report --stdio -q
    42.77%  ls       ls                [.] _init
    13.21%  ls       ld-2.24.so        [.] match_symbol
    12.55%  ls       libc-2.24.so      [.] __strcoll_l
    11.94%  ls       libc-2.24.so      [.] _init

We still have those two extra lines tho, food for another patch...
