I like the idea of the new ':/<oneline prefix>' notation, and gave it
a try, but all I could get was a segfault. It was dereferencing a NULL
commit list. Fix below. With it, this example now works:
$ mkdir .j; cd .j; touch f
$ git-init; git-add f; git-commit -mc f; echo x >f; git-commit -md f
$ git-diff -p :/c :/d
