Hi Nick,

I would like to thank you, since your message made me curious about git,
and I started using it. After reading a little bit, I was able to install
it, clone the org repository and revert the commit we were talking about
(that feels good). I can now use Org normally again. I just hope it's not a
very bad thing to do.
