Randy sent you a much better email than mine about it, but here it goes:

hmh@thorin:/tmp/f$ git init 
Initialized empty Git repository in .git/
hmh@thorin:/tmp/f$ cp /var/log/Xorg.0.log .
hmh@thorin:/tmp/f$ git add .
hmh@thorin:/tmp/f$ git commit -m "initial commit"
Created initial commit 4e5f9c4: initial commit

hmh@thorin:/tmp/f$ git commit -m "move commit"
 Created commit ed5f8d0: move commit
 2 files changed, 1260 insertions(+), 1260 deletions(-)
 delete mode 100644 Xorg.0.log
 create mode 100644 Xorg.1.log
hmh@thorin:/tmp/f$ git diff HEAD^.. -M       
diff --git a/Xorg.0.log b/Xorg.1.log
similarity index 100%
rename from Xorg.0.log
rename to Xorg.1.log

The key is that -M (or -C for that matter).  To be even more clear:
hmh@thorin:/tmp/f$ git diff HEAD^.. | wc
   2532   20098  134766
hmh@thorin:/tmp/f$ git diff HEAD^.. -M | wc
   4      13     103

So I really should have mentioned -M when I talked about git diffs :-(
