[PATCH v3 0/4] Teach git diff-tree --stdin to diff trees

Updated after Junio's comments. (Patch 1/4 and 4/4 have not changed but I'm resending them anyway for convenience.)

---

Karl Hasselström (4):
      Add test for diff-tree --stdin with two trees
      Teach git diff-tree --stdin to diff trees
      diff-tree: Note that the commit ID is printed with --stdin
      Refactoring: Split up diff_tree_stdin
