The newline is missing for error messages in add_default_attributes()

Before:

  # perf stat --topdown
  Topdown requested but the topdown metric groups aren't present.
  (See perf list the metric groups have names like TopdownL1)#

After:

  # perf stat --topdown
  Topdown requested but the topdown metric groups aren't present.
  (See perf list the metric groups have names like TopdownL1)
  #

In addition, perf_stat_init_aggr_mode() and perf_stat_init_aggr_mode_file()
have the same problem, fixed by the way.

Wait a bit till I push what I had to perf-tools-next, as it is not

OK, I'm doing the patch based on the mainline, and if I need to do it 
based on the perf-tools-next branch, I'll reissue it.

For patches for the currente perf development cycle the perf-tools-next
branch of:

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git

Should be used.

Hopefully soon we will transition to:

git://git.kernel.org/pub/scm/linux/kernel/git/perf-tools/perf-tools-next.git

And also:

git://git.kernel.org/pub/scm/linux/kernel/git/perf-tools/perf-tools.git

For fixes geared to the current merge window, when we are accepting just
fixes.

- Arnaldo

Thanks for the guidance, I'll resend the patch based on the 
perf-tools-next branch.

Thanks,
