Re: [PATCH v4 0/6] submodule: drop the top-level requirement

> Changes since v3:
> 
> * There are four new patches, three of which are style fixes for
>   existing tests and one fixes an existing error message to return a
>   more accurate path when recursing.
> 
> * You now cannot run "git submodule add <relative URL>" from a
>   subdirectory.  Because the interpretation of the URL changes depending
>   on whether or not remote.origin.url is configured, I have decided to
>   just ban this for now.  If someone comes up with a sensible way to
>   handle this then we can lift this restriction later.
> 
> * The "path" variable exported in "submodule foreach" now uses the
>   relative path and matches the "sm_path" variable.
> 
> * I audited the code again and fixed a few more cases that weren't
>   printing relative paths (notably "submodule init" and "submodule
>   foreach").
> 
> * More tests.
