Subject: [PATCH 05/10] perf sort: Calculate parent column width too

From: Namhyung Kim <namhyung.kim@....com>

When hists__calc_col_len() called, most of column length are refreshed
but it missed parent column.  So if the parent sort key was used along
with other keys rests will be misalinged since parent has no proper
column width.
