While I applaud being careful with submodules, I think this may be a bit
overeager, because empty (both not initialized as well as not populated)
submodules are fine.

In origin/bw/grep-recurse-submodules^6 you find
    int is_submodule_populated(const char *path)

that could be useful here, i.e. I'd imagine you'd change the condition to

    if (S_ISGITLINK(ce->ce_mode)
        && !is_submodule_populated(ce->name)) {
        ...

I guess that can come as a fixup later though.
