This reverts commit 9016d288f1cd03bf514fe84d537b203040e1ccf8. Tools that have no options are required by POSIX to support "--" so that conforming applications have a way to shield their operands from implementations that provide options as an extension. echo(1) is just an exception, so it is handled specially. See OPTIONS in https://pubs.opengroup.org/onlinepubs/9699919799.2018edition/utilities/V3_chap01.html#tag_17_04
