In the case where there is a sub_command, we execute this code:
if (sub_cmd_obj != nullptr) {
// Now call CommandObject::Execute to process and options in
// 'rest_of_line'. From there the command-specific version of Execute
will
// be called, with the processed arguments.
args.Shift();
sub_cmd_obj->Execute(args_string, result);
return result.Succeeded();
}
the `args.Shift()` statement has no effect, since `args_string` is computed
before we get here and is not recomputed after the shift. So either the
Shift() is superfluous or we should be re-generating the args string before
passing it through.
Can someone confirm which is correct?
