I just saw a PR where the changelog entry didn't have the top level indentation, i.e., it looks like this:

This is my multi line
change log
By Author

instead of

- This is my multi line
  change log
  By Author

And made me wonder, do we really need that top level indentation in every single file? We could make our scripts / towncrier simply add that instead, couldn't we?
