It's required, and this doesn't change; in Issue 7, the tsort OPTIONS sexion reads "None." and there are operands, so naturally XCU, 1.4 Utility Description Defaults, OPTIONS, Default Behavior: applies: Default Behavior: When this section is listed as "None.", it means that the implementation need not support any options. Standard utilities that do not accept options, but that do accept operands, shall recognize "--" as a first argument to be discarded. Best, наб
