Re: [PATCH v7 07/11] refs/refs-internal.h: new header file

> There are a number of constants, structs, and static functions defined
> in refs.c and treated as private to the references module. But we want
> to support multiple reference backends within the reference module,
> and those backends will need access to some heretofore private
> declarations.
> 
> We don't want those declarations to be visible to non-refs code, so we
> don't want to move them to refs.h. Instead, add a new header file,
> refs/refs-internal.h, that is intended to be included only from within
> the refs module. Make some functions non-static and move some
> declarations (and their corresponding docstrings) from refs.c to this
> file.
> 
> In a moment we will add more content to the "refs" subdirectory.
