I'd say it's correct to exit with an informative message, generally
speaking. Otherwise if you have a typo or something you'll never know.
Also this is the standard UNIX behavior:

$ ls --blah
ls: unrecognized option `--blah'
Try `ls --help' for more information.
$

"echo" is a special case, the Single UNIX Specification specifies
funky behavior for echo.
