Daniel Axtens fe0586347e script/execute: Avoid crash when using "$#" outside a function scope ... "$#" represents the number of arguments to a function. It is only defined in a function scope, where "scope" is non-NULL. Currently, if we attempt to evaluate "$#" outside a function scope, "scope" will be NULL and we will crash with a NULL pointer dereference. Do not attempt to count arguments for "$#" if "scope" is NULL. This will result in "$#" being interpreted as an empty string if evaluated outside a function scope.
