Subject[PATCH 18/18] perf report: Add report.group config option
Date
From: Namhyung Kim <namhyung.kim@lge.com>

Add report.group config option for setting default value of event
group view. It affects the report output only if perf.data contains
event group info.

A user can write .perfconfig file like below to enable group view by
default:

$ cat ~/.perfconfig
[report]
group = true

And it can be disabled through command line:

$ perf report --no-group
