The "broken" commit would need to be included in the commit-graph file
so its children can point to it using a graph position, but then it
would revert to parsing from the commit object (due to some new concept
storing "this is a bad commit").
If we decided to treat a timestamp of 0 as "probably broken, artificial
at best" then we wouldn't need the new indicator in the commit-graph
file, but this seems like quite a big hammer for a small case.
