Notes (series):
    v3:
    • Review feedback: check more in the test by inspecting the
      sequence editor
    
      Link: https://lore.kernel.org/git/5ed77fab-678d-4a06-bbd0-ea25462a7562@gmail.com/
    • Message: consistency with the other two messages:
      • Mention both commentChar and commentString
      • Commit footnote style: See <commit>
    v2:
    • Message: “hardcoded” (more common according to `git grep`)
