The echo command is actually required by POSIX not to accept any options.

Yes, we know that bash's built-in echo does not conform to POSIX. That is another story.
It should to, otherwise any script containing the line:
echo "$x"
That echo will *not* be the echo from coreutils.
Yes, I know that bash scripts echo with a builtin. That's why the subject line said "/bin/echo". I should have been more precise, and also put the "/bin/" in the body of the report.
Still, if the program exists, it ought to be correct in one sense or another. It should either be sensible and safe (i.e. accept "--") or POSIX (i.e. accept nothing).
