[PATCH] show changed tree objects with recursive git-diff-tree

This adds a "-t" flag to tell the raw diff output to include the tree
objects in the output when doing a recursive diff.

Since that's how the non-recursive output already handles trees and the
flag thus doesn't make sense without "-r", I made "-t" imply "-r".
