It depends: the main issue is the diff algorithm. Pijul's diff is not line-based, but rather "byte block"-based (which at the moment happen to be lines). This means that we could totally imagine more clever diff algorithms for specific use cases. I don't know anything about PCB design files, but an example application of this is to treat indentation and spaces as their own blocks.
