These files have been lightly modified in order to make their output more reproducible.

Changes:
- `\o /dev/null` has been added before commands that print LSNs since LSNs aren't reproducible
- `now()` has been replaced with a hardcoded timestamp string for reproducibility
- The test is run with `--quiet`, and the expected output has been trimmed accordingly
