Ahh, OK, because the helper accepts "--reference" "--reference=foo"
as a OPT_STRING whose value happens to be "--reference=foo", and
then uses
if (suc->reference)
argv_array_push(&child->args, suc->reference)
where suc->reference _is_ "--reference=foo" when invoking the
underlying "git clone", it cancels out.
Then it is OK.
In fact there is NO bug. It just is that update_clone subcommand
used a convention different from others that took the whole
--option=arg as a parameter to --reference option. It could be
argued that it is an API bug between git-submodule.sh and
git-submodule--helper, but nobody else goes through this "weird"
interface, so it is not worth splitting the patch.
