Adding quotes around --stat won't buy you anything since the shell will have removed the quotes by the time the argument is passed to echo, so an "obscure crazy" 'echo' will still see --stat as an option.

POSIX states that printf should take no options, so:

    printf --stat

should be safe, but some implementations do process options (and will complain about the unknown --stat option), therefore, best would be:

    printf '%s' --stat
