A recently added "commit-graph" datafile has learned to store
pre-computed generation numbers to speed up the decisions to stop
history traversal.
Is this ready for 'next'?
I see that you squashed the fix from [1], so I think this is ready to
go. Thanks!

The code has been taught to use the duplicated information stored
in the commit-graph file to learn the tree object name for a commit
to avoid opening and parsing the commit object when it makes sense
to do so.
Will merge to 'master'.

Precompute and store information necessary for ancestry traversal
in a separate file to optimize graph walking.

These have been queued for master for a few weeks. Is anything delaying
them? I'd love to see the community dogfood this feature by running the
following on their local repos:
git config core.commitGraph true
git show-ref -s | git commit-graph write --stdin-commits
Thanks,
