My understanding is that this is exactly by design.  The supermodule
tracks which commit in the subproject is bound to the tree location.

A mere act of changing something in the subproject directory is just a
single, incomplete step to create a new commit in the subproject and will
not be seen by the superproject's status.  Instead of this workflow:

> 	cd super
> 	vi newsuper
> 	vi existing_file
> 	cd sub
> 	vi newsub
> 	cd ..
> 	git status

the submodule support is geared toward supporting this layout:

	- "super" has a subproject X at "sub"

        - When you do a real work on the subproject X, you do so as if
          there is no supermodule.  IOW, subproject X has to be able to
          stand on its own.

One extreme case is you have a(nother) clone of subproject X that is
independent from "super", do the real work there and create new commit,
and update the subproject X inside "super".  In such a workflow, "super"
will never see an intermediate state between commits in the subproject
directory.
