Re: [PATCH v7 02/20] submodule--helper: refactor get_submodule_displaypath()

> From: Atharva Raykar <raykar.ath@gmail.com>
>
> We create a function called `do_get_submodule_displaypath()` that
> generates the display path required by several submodule functions, and
> takes a custom superprefix parameter, instead of reading it from the
> environment.
>
> We then redefine the existing `get_submodule_displaypath()` function
> as a call to this new function, where the superprefix is obtained from
> the environment.
