Subject: [PATCH 36/36] perf map browser: Exit just on well known key presses

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Initial motivation was to avoid the confusing exit when when '/' is
pressed in non verbose mode, as specified in the help line searches
are only available in verbose mode.
