Some submodule tests do some setup outside of a test_expect
block. This is bad because we won't actually check the
outcome of those commands. But it's doubly so because "git
add submodule" now produces a warning to stderr, which is
not suppressed by the test scripts in non-verbose mode.
This patch does the minimal to fix the annoying warnings.
All three of these scripts could use more cleanup of related
setup.

When fd47ae6a5b (diff: teach diff to display submodule difference with an
inline diff, 2016-08-31) was introduced, we did not think of recursing
into nested submodules.
When showing the inline diff for submodules, automatically recurse
into nested submodules as well with inline submodule diffs.

This happens, because we do not properly initialize the environment
in which the diff is run in the submodule. That means we inherit the
environment from the main process, which sets environment variables.
(Apparently we do set environment variables which we do not set
when not in a submodules, i.e. the .git directory is linked)
This commit, just like fd47ae6a5b (diff: teach diff to display
submodule difference with an inline diff, 2016-08-31) introduces bad
test code (i.e. hard coded hash values), which will be cleanup up in
a later patch.

Teach git-diff and friends a new format for displaying the difference
of a submodule. The new format is an inline diff of the contents of the
submodule between the commit range of the update. This allows the user
to see the actual code change caused by a submodule update.
Add tests for the new format and option.
