helpOption does not support more than 2 flags

For example, using .helpOption ('-h, --help, --something-else') and running with --something-else results in

error: unknown option '--something-else', while -h and --help still work.

Use case: not sure about others, but me personally, I'd also like to add -? as an extra help flag.

Options support a short flag and a long flag, and this applies to the built-in version and help options too.

I see, so I guess no luck adding a third option.
