Re: [PATCH 2/2] submodule-helper: fix indexing in clone retry error reporting path

> 'git submodule--helper update-clone' has logic to retry failed clones
> a second time. For this purpose, there is a list of submodules to clone,
> and a second list that is filled with the submodules to retry. Within
> these lists, the submodules are identified by an index as if both lists
