[PATCH 09/37] perf hists: Fix period symbol_conf.field_sep display

From: Arnaldo Carvalho de Melo
Date: Tue Dec 11 2012 - 17:49:31 EST


From: Jiri Olsa <jolsa@xxxxxxxxxx>

Currently we don't properly display hist data with symbol_conf.field_sep
separator. We need to display either space or separator.
