Thank you very much for pointing out this document information to me.
The above submodules status for my case were achieved by the following
command:

$ git submodule update --init --recursive --remote

As you can see, this will cause the status denoted by '+', i.e., the
currently checked out submodule commit does not match the SHA-1 found
in the index of the containing repository. I'm not sure if this is
harmful.
