The above two hunks both assume that the super_prefix option is
usable only from the top-level (i.e. opt->prefix_length == 0) and
also "--no-full-name" (which is the default) cannot be used. The
only invoker that runs "grep" with "--super-prefix" is the "grep"
that runs in the superproject, and it will only run us from the
top-level of the working tree, so the former assumption is OK.
It is a bit unclear to me how the "relative" and "--recurse-submodules"
would interact with each other, though.
