Re: [PATCH 3/9] submodule: add gitdir path config override

> This adds an ability to override gitdir paths via config files
> (not .gitmodules), such that any encoding scheme can be changed
> and JGit & co don't need to exactly match the default encoding.
> 
> A new test and a helper are added. The helper will be used by
> further tests exercising gitdir paths & encodings.
