Continuing with the previous review, which concentrated on what
happens in the superproject; let's see what happens in the recursive
invocation in a submodule.
So a recursively spawned "ls-files --submodule-prefix=sub/" finds
a path in the index PATH and forms "sub/PATH" in "name". From here
on, where we used to match pathspec against ce->name, we would be
matching it against name->buf.

This is primarily what happens in the superproject to decide if the
submodule is worth showing. When we are in a submodule, we can
descend into subsubmodule (if our ls-files run in the superproject
passed --recurse-submodule down) from here.

This is interesting bit to see what happens in the recursive
invocation. It uses the usual match_pathspec(), as we want to be
precise and correct, iow, we do not want to use DO_MATCH_SUBMODULE,
aka "it might be worth descending into submodule".

The prefixing is taken care of by write_name(), so it is correct to
use ce->name here.

OK, everything I saw so far for the recursive invocation here makes
sense.
Thanks.
