Adding integration tests and adding translate is two pr's on their own I think because this doesn't have integration tests yet and doesn't have a translation utility, theres a few details about adding both of those because this utility is unique. Going to work on both of those in seperate PR's before updating this one |

The coreutils multicall binary doesn't use clap for argument parsing - it manually handles a few known options (--list, --version, --help) and treats everything else as a utility name.
When given an unrecognized option like
--unknownor-/, it was outputting:This was causing the
usage_vs_getopt.shGNU test to fail because it expects the standard error format:This PR adds detection for option-like arguments (starting with
-) and outputs the proper error message.
