From 9ffad987ff565999d91fc2783dd77f08094a743b Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 3 Sep 2012 11:53:07 +0900 Subject: [PATCH] perf hists: Handle field separator properly 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.
