This surprised me a bit, because:

    $ which grep
    /usr/bin/grep
    $ grep foo -i foo.txt
    FOO

and even

    $ grep foo foo.txt -i
    FOO

Looking at the source, the difference seems to be getopt vs getopt_long
(and there is a few other base programs that use getopt_long). POSIX
doesn't seem to mention any --options for grep either.
