Re: [PATCH v4 0/5] git-add: Skip submodules with ignore=all unless --force and explicit path used

> The ignore=all configuration for submodules is currently honored by status
> and diff, but not by add. This inconsistency causes friction when working
> with submodules:
>
>  * Developers unintentionally stage submodule updates, leading to conflicts
>    and unnecessary changes.
>  * Tracking branches in submodule configs causes friction as updates to the
>    submodule SHA1 are added without intent.
>
> This patch aligns git add with the behavior of status and diff:
>
>  * Submodules marked ignore=all are skipped by default.
>  * Attempting to add such a submodule explicitly now requires --force.
>
> A submodule can frictionless track a branch in the configuration or manually
> switched to and use update --update --remote without unintentionally add the
> changes to the super-project.
>
> Tests that previously added submodules without --force have been updated
> accordingly. A new test is added to test the behavior of git add with and
> without --force.
