As for your concern if the patch file is correctly formed: It applies, and it adds those .blends under new data/graphics/Elefant-Cimpletoon-Renderers/ directory. So seems fine for that part.
Your git.email seems to be "Elefant@Elefant-PC.lan" as the Author-field of the commit is: "Author: Elefant <Elefant@Elefant-PC.lan>"
Do you want to keep it that way, or to rework it some way? We do have commits that point emails like "..-no-reply@..." etc, but I don't remember invalid domain part ever being used before.
If you want, I can reset the author field of this patch for you. Just tell what email you want used.
Just so that we would get this first one handled.
Changed email address
Preferably, if someone wants to contact me, they should reply to a ticket of mine or message me on the forums.
I wasn't quite sure what versions to target, but maybe these get used for some 3.1 work?
Setting status to "Accepted" means that the review period (there's no better status for that in OSDN) started. People have at least 36h to comment.
Any version should be fine.
