While I see why "ls-files --recurse-submodules" sounds nice ("hey, I
can get list of _all_ the files here"), and I am quite happy with
the quality of implementation (not just the code but its
documentation and test) especially from a first-time contributor, I
am not quite sure what the utility of this new feature would be,
especially given that the command is a plumbing, i.e. meant to be a
useful building block for scripts.

If I get

        $ git ls-files --recurse-submodules

out of the command, what can I do with it without knowing where the
submodule boundaries are?  It's not like I can just do

        git ls-files --recurse-submodule |
        while read path
                git update-index --add "$path"

when "lib/" is a submodule.  Instead, I'd need to go to "lib/" and
then add "Makefile" and "" from there.

We used to do that when we didn't know better.

Please don't do things outside test_expect_* block, especially in a
new script.
