Yes I know it will delete ignored files. But I don't want it to delete
some files. There is no way I can tell Git to do that.

It's the same with merge/checkout's overwriting problem. Once the
initial surprise is over, I want control over what files I want Git to
just delete and not annoy me, what Git should not delete.
