[PATCH 0/3] fix "diff --raw" on the work tree side

The second patch fixes the inconsistency between "git-diff --raw" and
"git-diff-{index,files} --raw" when they are used for submodules.

The third one is a bit controversial and changes the semantics and
existing callers and won't be considered for 1.5.5.

Junio C Hamano (3):
      diff-lib.c: constness strengthening
      diff: make sure work tree side is shown as 0{40} when different
      diff: show submodule object name when available even on the work tree side
