That's right. It's a good thing.

Hehe! I wasn't aware of this project :)

That will be a great day when I will be able to send a not line/space

Hmm I ran this script and it warned about a non conventional format

I can't test the master branch yet. But as far as I read the diff, it
seems correct.

Thanks Ingo :)
I will improve it as I can...
