Any program that uses getopt() to scan its command-line arguments will
be able to handle "--" as an "end of options" marker.

I really don't like the use of "-" for this, as that is conventionally
an indication that stdin is to be used where a file would normally be
named.  Things are confusing enough without doubling up on meanings.
