Currently, 'perf list --raw-dump' requires extra arguments
(e.g., hw) to invoke, which breaks bash/zsh completion
(perf-completion.sh).
$ perf list --raw-dump
Error: unknown option `raw-dump'
usage: perf list [hw|sw|cache|tracepoint|pmu|event_glob]
After,
$ perf list --raw-dump
cpu-cycles instructions cache-references cache-misses ...

Why does this need to be a global static variable? Can't it be moved

Thanks for fixing this. Actually the --raw-dump option is intended to
support shell completion and not to be used directly. I didn't update
the completion script for a while so didn't notice it. It seems like
recent updates of the option parsing code broke this.

So I'd like to keep the usage string as is and mark the option as
hidden - i.e. using set_option_flag(list_options, 0, "raw-dump",
PARSE_OPT_HIDDEN) before calling to parse_options().
With that,
