[ 005/150] perf hists: Fix period symbol_conf.field_sep display

[Greg Kroah-Hartman]

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Olsa <jolsa@xxxxxxxxxx>

commit c0d246b85fc7d42688d7a5d999ea671777caf65b upstream.

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