It's the same thing in France, but that's why the OP repo is great: you can see the actual change as a usual diff (https://github.com/steeve/france.code-civil/commit/0d5337622...).

I'm not sure how they do it, but I guess that it wouldn't be extremely hard to have a small grammar to automatically convert the legalese patch into an actual git patch (most of the time, the sentences which wrap the editions are the sames).
