No, the fact that they output help text is because "--help" was asked for, and they do support "--help".Support? I would expect that to be documented. If a utility does not document an option, how can I be sure what would happen if I used it?
So maybe something like "All builtins, with the exception of `:', `echo', and `[/test', accept --help as a special option. If --help is supplied, the builtins output a help message and exit with a status of 2."
Should I somehow *assume* that "--help" is supported?
You can in the case we're discussing, but only because bash is a GNU
program and `--help' is part of the GNU coding standards.
