Depends on your definition of today, but with the patch below I
sent today, you can say "diff-tree -p $tag $(cat .git/HEAD)".

    Subject: [PATCH] Rename and extend read_tree_with_tree_or_commit_sha1
    Date:	Thu, 28 Apr 2005 12:15:43 -0700
    Message-ID: [ref]

    This patch renames read_tree_with_tree_or_commit_sha1() to
    read_object_with_reference() and extends it to automatically
    dereference not just "commit" objects but "tag" objects.  With
    this patch, you can say e.g.:

        ls-tree $tag
        read-tree -m $(merge-base $tag $HEAD) $tag $HEAD
        diff-cache $tag
        diff-tree $tag $HEAD
