Re: [PATCH] refs.h: rename submodule arguments to submodule_path

> In submodule land we carefully need to distinguish between the path of a
> submodule and its name.
>
> The path of a submodule is the path that is recorded in the working tree
> of the superproject and describes where the submodule is bound to the
> superprojects tree.
>
> The name as introduced in 941987a554 (git-submodule: give submodules
> proper names, 2007-06-11) exists to track submodules across renames of
> submodules. It is also used for the internal path in .git/modules/<name>
> to store the git directory of the submodule inside the superproject.
