Subject: [PATCH 3/5] perf hists browser: Show folded sign properly on --hierarchy
From: Namhyung Kim <namhyung@...nel.org>
When horizontal scrolling is used in hierarchy mode, the folded signed
disappears at the right most column.
Committer note:
To test it, run 'perf top --hierarchy, see the '+' symbol at the first
column, then press the right arrow key, the '+' symbol will disappear,
this patch fixes that.
