I am open for reverting this if it causes trouble in established workflows. 

But the problem with committed .rej files is real too, and I'm not sure how to solve that without using .gitignore. I think we need to either:

A) establish that this new behavior is much worse than the risk for integrating unwanted files (if so, we can just revert this), or

B) find another solution that allows us to remove this change but still catch the unwanted .rej and .orig files.

I don't have any good suggestions on B, and I am not sure how we could decide if A is applicable or not.
