The idea behind not skipping gitlinks here was to be compliant with
what we have in the working tree. In 4fd683b ("sparse-checkout:
document interactions with submodules"), we decided that, if the
sparse-checkout patterns exclude a submodule, the submodule would
still appear in the working tree. The purpose was to keep these
features (submodules and sparse-checkout) independent. Along the same
lines, I think we should always recurse into initialized submodules in

Sorry if I missed it in the code, but do you check whether the
submodule is initialized before descending into it, or do you descend
into it based on it just being a submodule?

We only descend if the submodule is initialized. The new code in this
patch doesn't do this check, but it is already implemented in
grep_submodule() (which is called by grep_tree() and grep_cache() when
a submodule is found).
