This fixes "git diff", "git diff-files" and "git diff-index" to work correctly under worktree setup. Because diff* family works in many modes and not all of them require worktree, Junio made a nice summary (with a little modification from me): * diff-files is about comparing with work tree, so it obviously needs a work tree; * diff-index also does, except "diff-index --cached" or "diff --cached TREE" * no-index is about random files outside git context, so it obviously doesn't need any work tree; * comparing two (or more) trees doesn't; * comparing two blobs doesn't; * comparing a blob with a random file doesn't; Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
