Subject: [PATCH 2/5] perf hists: Handle field separator properly
From: Namhyung Kim <namhyung.kim@....com>
When a field separator is given, the output format doesn't need to be
fancy like aligning to column length, coloring the percent value and
so on. And since there's a slight difference to normal format, fix it
not to break backward compatibility.
