Re: [PATCH v2 04/10] submodule--helper: convert "foreach" to its own "--super-prefix"

> As with a preceding commit to convert "absorbgitdirs", we can convert
> "submodule--helper foreach" to use its own "--super-prefix", instead
> of relying on the global "--super-prefix" argument to "git"
> itself. See that earlier commit for the rationale and background.
