I suspect the goal was to use a tool such as checkpatch, or
get_maintainer without -f.  An implementation using git archive should
still work (with the help of a tar diff-ing program with the EMPTY
feature ;-)), but as UI that might be less discoverable than building
it into git diff.

Personally, I liked both the

  git diff $(</dev/null git hash-object -t tree --stdin) $rev

and

  git diff --root $rev

suggestions.  That may be from a warped sense of aesthetics.

Cheers,
Jonathan
