[patch] How can I show a patch to the list using Git?

[Uwe Stöhr]

As suggested I branched the Git master to develop a new feature. Now I think this feature is now 
ready and I want to show it on the list but how can I do that?

I tried to generate a patch from my branch but I only get a success message and 
no file is generated.
I can also not push it to somewhere as i don't know where.

regards Uwe
