Do everything we can to help macOS users to NOT commit .DS_Store

Make or append to a global .gitignore file, then do the appropriate Git config command? Happy to work on a PR if desired.

I think it's probably safe to add .DS_Store into the use_git function. It's handy for non-Mac users, too, as I can imagine a scenario where someone creates a repo, and then a Mac user contributes to it, uses git add ., and inadvertently commits a bunch of .DS_Store files.

Modifying global .gitignore through use_git_config would also be a nice feature to have, but as that function currently doesn't touch those files, maybe that should be left alone.

I have it in my ~/.gitignore.

If we start touching that file, we should also add .Rproj.user to it.

And also .Rhistory (since that's an easy way to accidentally share credentials).

What we call such a function? It's a bit different because it acts globally, but I think it's a safe operation to perform.

It feels like we’re developing a notion of a system “health check” and this is a check specific to git and macOS.

Maybe we could call it vaccinate_git() (we can't use immunise() for hopefully obvious reasons)

maccinate_git()? 😉
