Actually, all coreutils (and most other well-behaved programs) that take options and arguments also take -- as a delimiter to allow all subsequent parameters to be treated as arguments and not options - it is the behavior standardized by POSIX.  See `info Coreutils' under the chapter 2 Common options.  A good rule of thumb in scripting is that if you are expanding an arbitrary variable and don't know whether it will start with a leading -, then you should be using a -- delimiter.
