Recursive invocations of submodule update/status preserve all arguments,
so executing
git submodule update --recursive -- foo
attempts to recursively update a submodule named "foo".
Naturally, this fails as one cannot have an infinitely-deep stack of
submodules each containing a submodule named "foo". The desired behavior
is instead to update foo and then recursively update all submodules
inside of foo.
This commit accomplishes that by only saving the flags for use in the
recursive invocation.

As suggested by Jonathan Nieder, I've included a test for
`git submodule status --cached --recursive -- nested` to verify
that the flags are preserved but the paths aren't.
