Thanks :-)

Yes, we do. Some options which are defined for timechart are undefined
for record (like -i, -o, etc), so we want to get an error in case of wrong
options.
And we separate usage, because it's different in timechart:
"perf timechart [<options>] {record}",
and record:
"perf timechart record [<options>]",
We may share usage, but we need it to be something (confusing?) like:
"perf timechart [<options>] {record [<options>]}",
