Subject[PATCH 1/2] perf ui/hist: Fix output for 100.00%
Date
From: Namhyung Kim <namhyung.kim@lge.com>

Current hpp format functions assume that the output will fit to 6
character including % sign (XX.YY%) so used "%5.2f%%" as a format
string. However it might be the case if collapsing resulted in a
single entry which has 100.00% (7 character) of period. In this case
the output will be shifted by 1 character.
