In my own code I have given up on lining up either fields or the braces. As long as closing brace (or a key|field) is placed in a same column or after of opening brace (or previous key|field) (via indentation of expanding tabs), I am good.

Anyone or anything (commit hook for example) else is more than free to mangle that to their own liking.

I do not understand this part if you care to explain ...

And that's not even getting into the fact that it completely dropped the ball on offering the ability to spot differences between the lines at a glance when it could easily have done so.
