Thanks - I've reviewed up to this patch, and patches 1 and 2 look good.

Optional: Reading this header file alone makes me think that the 3rd
argument can be NULL, but it actually can't. I would name it
"extra_args" and add a comment inside "struct set_gitdir_args"
explaining (e.g.):
/*
* Any of these fields may be NULL. If so, the name of that directory
* is instead derived from the root path of the repository.
*/
