No, because 'echo' is one of the few exceptions to the rule, in that
POSIX specifically mandates that it NOT recognize -- as an
end-of-options marker.

But then the "-n" shouldn't be printed either, should it? "-n"
is a valid command line option for coreutil's /bin/echo (and
the bash builtin, too).

This doesn't seem reasonable. Posix says also "Implementations
shall not support any options", i.e. coreutil's echo is violating
Posix, anyway.
