Yes, and because "diff" and "format-patch" are for producers of, and "apply" and "am" are for consumers of a patch, which are likely to be different people, "apply" or "am" should never pay attention to "diff.noprefix". It is a different issue if we should have - format-patch.noprefix, which defaults to the same as diff.noprefix, but allows people to configure "format-patch" differently from "diff" and "show" - am.pvalue, which defaults to 1, but can be set to e.g. 0 to accept format-patch output from those who set format-patch.noprefix to true I haven't thought things through, but offhand I do not see why we shouldn't. But I am reasonably firm on that diff.noprefix should never affect anything on the "apply/am" side.
