That is better.

I'm not sure this is an improvement. To me the original code is just
fine. Also, I don't think writing an 'expect' file belong in a setup
step.

Additionally I would do this change in a separate patch.

That's also good.

All the changes in this patch look good to me, however, they are smashed
together in a way that makes the review harder, I see:

 1. Use test_commit
 2. Rename out to actual
 3. Use >actual instead of > actual
 4. Use test_seq instead of $numbers
 5. Use branches.sorted instead of branch$i
 6. Use test_config instead of git config
 7. Use internal sed 's/^ //' instead of outside cat

I'm on-board with 6 out of 7, but if these were done it at least 2
patches, they would be clearer. I in fact would prefer one patch per
change (although maybe squash 3 with 2).

Cheers.
