According to POSIX, echo doesn't take options. It is specified
that "Implementations shall not support any options."
(We have options, though,  so things are complicated.)

The POSIX specification of "echo" is going to change in a future
version. See: http://austingroupbugs.net/view.php?id=1222
and http://austingroupbugs.net/view.php?id=1222#c4375 for the
accepted new text.

I see.

IMHO they should have kept the "no args allowed" for echo
("in the late 70s") and should have introduced a new tool
"eecho" instead.
