- * it would need to complete its operation.  If "permissions" is NULL,

- * When a command is called with non-NULL "permissions", some arguments

- * the output of another function, so is not known at permissions time.
- * The permissions of leaf-node functions (those that have only literal
- * strings as arguments) will get appended to the permissions of the
- * functions that call them.  However, to be completely safe, functions
- * that receive a NULL argument should request the broadest-possible
- * permissions for the range of the input argument.
