FWIW, you can also do this as:
  ldiff = log -p -1 --format=format: --

> ldifft = "!git difftool `git rev-list --reverse -n 2 HEAD -- $1` -- $1"

I don't know that you can do something equivalent with difftool. I
suppose you could do the above with "GIT_EXTERNAL_DIFF=<some difftool
wrapper> git ldiff", but that's not very helpful.
