Subject[PATCH 03/10] perf sort: Fix --sort pid output
Date
From: Namhyung Kim <namhyung.kim@lge.com>

The "pid" sort key prints "Command: Pid" output but it's misaligned.
It's because of the offset of 6 was added to the column length during
the calculation in order to reserve an space for Pid part but it isn't
honored when printed. The output before this patch was like this:

# Overhead Command: Pid Shared Object
# ........ ............. .................
#
99.70% noploop:17814 noploop
0.29% noploop:17814 [kernel.kallsyms]
0.01% noploop:17814 ld-2.15.so

Fix it by subtracting 6 for printing comm part.
