The same.
But I change my mind in my production environnement when a day
we changed the args used to launched an exe within a .sh, so the exe
silenty return 0 to the sh
but do nothing else print the notice. Now, I prefer to distinguish
between -? or --help wich are
notice calling and empty call which can be invalid or valid (depend on
the exe).
