Yeah.  René wanted this for _human consumption_, not mechanical patch
application, so "hardcoding" literally there in the very low level of the
diff callchain is not quite right (it would affect format-patch which is
primarily for mechanical application).

I guess you could make the hardcoded value 1 for everybody else and 0 for
format-patch.
