From: Namhyung Kim <namhyung.kim@lge.com>
The -s (--sort) option was processed after normal option parsing so that it cannot call the parse_options_usage() automatically. Currently it calls usage_with_options() which shows entire help messages for event option. Fix it by showing just -s options.
$ perf report -s help Error: Unknown --sort key: `help'
usage: perf report [<options>]
-s, --sort <key[,key2...]> sort by key(s): pid, comm, dso, symbol, ...
