  # Ensures a Gerrit Change-Id line is included in the commit message.
  #
  # It may seem odd to do this here instead of in a prepare-commit-msg hook, but
  # the reality is that if you want to _ensure_ the Change-Id is included then
  # you need to do it in a commit-msg hook. This is because the user could still
  # edit the message after a prepare-commit-msg hook was run.
