The help description for --switch-output looks like there are multiple
comma separated fields. But it's actually a choice of different options.
Make it clear and less confusing.
Before:
% perf record -h
...
--switch-output[=<signal,size,time>]
Switch output when receive SIGUSR2 or cross size,time threshold
After:
% perf record -h
...
--switch-output[=<signal or size[BKMG] or time[smhd]>]
Switch output when receiving SIGUSR2 (signal) or cross a size or time threshold
