...but not with /bin/echo, that's why i was asking.

j@uriah 54% /bin/echo -- '-n\n'
-- -n\n

OTOH, if you were asking for getopt, consider:

j@uriah 55% /bin/echo "- today's a great day -"
- today's a great day -

vs. the getopt(3)ified version:

j@uriah 56% /tmp/echo/echo "- today's a great day -"
echo: illegal option --  
echo: illegal option -- t
echo: illegal option -- o
echo: illegal option -- d
echo: illegal option -- a
echo: illegal option -- y
echo: illegal option -- '
echo: illegal option -- s
echo: illegal option --  
echo: illegal option -- a
echo: illegal option --  
echo: illegal option -- g
echo: illegal option -- r
echo: illegal option -- e
echo: illegal option -- a
echo: illegal option -- t
echo: illegal option --  
echo: illegal option -- d
echo: illegal option -- a
echo: illegal option -- y
echo: illegal option --
