All right.  Nice.

Looks good to me.

OK, include in continuous integration.

Good, it is documented in README for tests.

All right, we need to ensure that 'git commit-graph write' is not run
automatically, otherwise split / incremental commit-graph tests would
not work.

We also need to ensure that '--changed-paths' is not added
automatically, so that we can test that commit-graph does not include
Bloom filters chunks if not requested.

OK, otherwise it would screw up checking the content of commit-graph
with 'test-tool read-graph'.

Same here.

Looks good to me.
