this is the case I have to use:

```
Example of a patch submitted by a Co-developed-by: author::

    From: From Author <from@...hor.example.org>

    <changelog>

    Co-developed-by: Random Co-Author <random@...uthor.example.org>
    Signed-off-by: Random Co-Author <random@...uthor.example.org>
    Signed-off-by: From Author <from@...hor.example.org>
    Co-developed-by: Submitting Co-Author <sub@...uthor.example.org>
    Signed-off-by: Submitting Co-Author <sub@...uthor.example.org>
```

Do you think another case applies?

Please see Rasmus' reply, i.e. we are using Rust's own formatting
machinery (the compiler validates the format string and creates an
object that represents the formatting to be done).

Thanks for taking a look!

Cheers,
Miguel
