Before you get too married to the name "graph", is it reasonable to
assume that the commit ancestry graph is the primary "graph" that
should come to users' minds when a simple word "graph" is used in
the context of discussing Git? I suspect not.
Let's not just call this "core.graph" and "packed-graph", and in
addition give some adjective before "graph".
