I agree that --format leads to a much prettier solution. Unfortunately --format seems to turn off -z (at least in msysgit):

$ git --version
git version 1.6.3.2.1299.gee46c
$ git log -p > L1
$ git log -p -z > L2
$ diff L1 L2 | wc
   2415    4347   62889
$ git log -p --format=%s > L1
$ git log -p -z --format=%s > L2
$ diff L1 L2 | wc
