Re: [RFC/PATCH 1/2] submodule: implement `module_list` as a builtin helper

    $ git submodule--helper module_list

Why would you use an underscore in here as opposed to a dash?

Simply because the diff would be easier to read; the callers used to
call module_list shell function, now they call the subcommand with the
same name of submodule--helper.
