I know. I went this this struct because I really hate to write lots of
NULL without names

    repo_set_gitdir(gitdir, NULL, NULL, NULL, ...);

but I could not find a nicer way to make the whole struct optional,
not without repeating more code or using preprocessor. Given that this
function has 3-4 call sites max, I think it's still ok.
