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 ...
