A submodule really is part of the parent tree, so it is very natural to
add the link to the submodule commit into the GIT tree data structure.
In addition to links to blobs and other trees, they can now also hold
a link to a commit, which in turn has the pointers to the submodule tree
and its history.  In order to differenciate a submodule entry with
normal file or directory entries, they get a special file mode.

Erm... isn't a _type_ of tree entry saved somewhere? Currently it can
be only 'tree' or 'blob', what you do is adding 'commit' (then permissions
are permissions of top tree of module, of course).

It is saved inside the object which is being refered to.
Right now tree objects are also identified by their file mode and not
by the type of object which is referenced.

By the way, in todo branch, in Subpro.txt, there is talk about adding
link to submodule trees in _commit object_... well link to submodule tree
or commit, with the "mount point".

But isn't the submodule really part of the tree?
Right now the commit is used to construct the history of one project.
And a submodule is not part of the history of the parent, it is part
of the parent's tree.
