[PATCH 7/7] Add t/t7401 - test submodule interaction with remotes machinery

[Mark Levedahl <mlevedahl@gmail.com>]

This adds a sequence of tests to assure that the following two sequences
work:

	git clone -o frotz <someurl> foo
	cd foo
	git submodule init
	git submodule update

This should result in the master and subproject having "frotz" as the
name of the default remote (and origin undefined).

Then, in the same working directory
	git remote add fork <some url>
	git fetch fork
	git checkout --track -b fork fork/<somebranch>
	git submodule init
	git submodule update

will retrive new submodules from remote "fork", and define fork in the
existing modules. Origin remains undefined.

Note: this latter case is a clear motivation for overriding "origin": after
the second test, the various submodules would have different ideas of
remote "origin": these would point to different servers. This would
entirely prevent the top-level branch.<name>.remote machinery from
controlling the project as there is no uniform naming of remotes.

+
+This test verifies operation of submodules using multiple remotes and
+differing remote per top-level branch.  This includes ability to name the
+default something other than origin, to follow the top-level
+remote.<branch>, and to propagate definition of new remotes down to
+submodules as needed.
