This problem was reported in
https://github.com/git-for-windows/git/issues/2677, but the problem actually
lies with git diff --raw, and it seems that the bug has been with us ever
since--intent-to-add was introduced.

Johannes Schindelin (3):
  diff-files: fix incorrect usage of an empty tree
  diff-files --raw: handle intent-to-add files correctly
  difftool -d: ensure that intent-to-add files are handled correctly
