From: Jacob Keller <jacob.keller@xxxxxxxxx>
git submodule--helper clone usage specified that paths come after the --
as a sequence. However, the actual implementation does not, and requires
only a single path passed in via --path. In addition, argc was
unchecked. (allowing arbitrary extra arguments that were silently
ignored).
Fix the usage description to match implementation. Add an argc check to
enforce no extra arguments. Fix a bug in the argument passing in
git-submodule.sh which would pass --reference and --depth as empty
strings when they were unused, resulting in extra argc after parsing
options.

After adding argc check to my new sanitize-config subcommand, I realized
that submodule--helper clone was the only one without an argc check.
When I went to add it, I realized the usage was incorrect, and the
implementation in git-submodule.sh results in extra arguments being
passed.
I am not sure this is the best way to resolve these, but I wanted to
include it since I think silently accepting extra arguments we don't use
is bad.
