I do think atomic ref transactions are a nice idea, and would probably
not be too hard to implement these days (the main thing is just
refactoring the deep call stack in git-fetch).

It's possible it could be annoying when you have a single broken ref
(and would prefer to just ignore it), but that _should_ be the rare
case.
