Subject: [PATCH 03/23] perf hists browser: Add e/c hotkeys to expand/collapse callchain for current entry

From: Jiri Olsa <jolsa@...nel.org>

Currently we allow only to expand or collapse all entries in the browser
with 'E' or 'C' keys. Allow user to expand or collapse only current
entry in the browser with e or c key.
