AFAIK, that's wrong (that's why I didn't include that in my script).

The original attribute refers to the file in which this translation was used. So if you have a `dashboard.html.twig` in which you have a `dashboard.label_body` label, the original attribute is `dashboard.html.twig`. If you have another translation message, let's say `homepage.welcome` inside `home.html.twig`, you should create a new file element and give it the attribute `home.html.twig`.

Because these files aren't really known in Symfony and because you are able to use it on different files, Symfony decided give it the value `file.ext`. This is also wrong, but less wrong.
