At least in the original design of Git, that would fundamentally be
impossible, as Git _only_ cares about paths that are in the index,
so a new file won't be in the picture until it is added. Because a
change is shown as "A"dded by the diff family of commands only when
the old side lacks a path that appears in the new side, there is no
way "diff-files" that compares the index and the working tree would
see a path that is missing from the old (i.e. the index) side.
