To clarify (and I should have said) I meant it'll include only packed commits in the mode Karl Ostmo invoked it in, as Derrick points out.

But yeah, you can of course give it arbitrary starting points, but needing to deal with those sorts of caveats makes it rather useless in practice for the sort of use-case Jakub mused about, but more importantly a full XML dump of the graph isn't going to get much of a benefit from the commit graph, it helps with algorithms that want to avoid those sorts of full walks.
