#1199347 — [PATCH 2/8] perf, tools: Do not include escape sequences in color_vfprintf return

From: Andi Kleen <ak@linux.intel.com>

color_vprintf was including the length of the invisible escape
sequences in its return argument. Don't include them to make
the return value usable for indentation calculations.

v2: Add comment, rebase
