Subject: [PATCH 17/21] perf list: Unify metric group description format with PMU event description

From: Michael Petlan <mpetlan@...hat.com>

PMU event descriptions use 7 spaces + '[' or 8 spaces as indentation.
Metric groups used a tab + '['. This patch unifies it to the way PMU
event descriptions are indented.

BEFORE:

  $ perf list
  [...]
  Metric Groups:

  DSB:
    DSB_Coverage
	  [Fraction of Uops delivered by the DSB (aka Decoded Icache; or Uop Cache)]
  [...]

AFTER:

  $ perf list
  [...]
  Metric Groups:

  DSB:
    DSB_Coverage
         [Fraction of Uops delivered by the DSB (aka Decoded Icache; or Uop Cache)]
  [...]
