So, having read 4/8 and this I wonder why
refs_resolve_ref_unsafe_with_errno() is needed at all. It's just a
wrapper that sets errno to a variable you give it, but we could just
document that tha caller should check errno.

So far I haven't seen anything that suggests the below diff-on-top
wouldn't be OK (and all tests pass with it). It steps on the toes of
some of my earlier suggestions, but I'm doing these one-at-a-time.

In any case the comment I adjusted seems like something you should
adjust to. It looks like a TODO for having the sort of function you've
just implemented in refs_resolve_ref_unsafe_with_errno().
