Which version of Git got the --batch option to git-cat-file? It might
be possible that default Git in Debian (testing) or Ubuntu doesn't
have this option. Maybe we could still have the original behaviour as
a fallback.

Otherwise, the patch looks allright. It took me a bit of time to see
why we need the new run_background() function (but in my current Git,
1.5.3.4.206.g58ba4, there wasn't such an option; I had to upgrade).

Thanks.
