Re: [PATCH 0/8] Change midx.c and midx-write.c to not use global variables

> Similar to the earlier patch series on cleaning up packfile.c and
> removing usage of global variables [1], we change the midx.c and
> midx-write.c files to no longer use global variables.

> This is done by the following:
>   - Usage of repository variable already available in existing structs.
>   - Passing down repository variable from other subsystems.
>   - Modifying all subcommands to obtain repository variable from the
>   command in `builtins/` and passing down the variable from there.

> The biggest change is in the first commit, wherein we modify all
