Interactively, I invariably use 'grep foo *.c' without the '--' and it works just fine because the files under my control have names that do not start with '-'. This is standard practice and simplifies the common-usage examples. So although '--' should (and does) appear in examples to document a defensive measure for scripts that must work even in nonstandard environments, '--' needn't be used in examples everywhere that it could conceivably apply.
