From 670ab5d21c7e168c89a36fdd2c69fb7af63d35a1 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 22 Oct 2012 16:12:23 +0900 Subject: [PATCH] perf help: Fix --help for builtins It seems that commit cc5848213329 ("perf help: Remove use of die and handle errors") caused the problem - it changed the initial value of 'help_format' from HELP_FORMAT_MAN to HELP_FORMAT_NONE. This broke the --help option for all builtins, that would produce no output, while 'man perf-top' would work it MANPATH is properly setup.
