BUG in http-backend.c > http.receivepack

[Springer, Stephan]

Hello Guys,

I found bug in http-backend.c with config-flag "http.receivepack"  You describe 
in our documentation: "This serves git send-pack clients, allowing push. It is 
disabled by default for anonymous users, and enabled by default for users 
authenticated by the web server. It can be disabled by setting this item to 
false, or enabled for all users, including anonymous users, by setting it to 
true."
That cannot work, while svc-enable less than 0. See attachment 

I tested with Centos 6.x,  Nginx 1.0.15 and Git 2.2.0-rc3 and Git 2.1.3

I hope you understand me and I don´t talk nonsense. My English a little rusty 
and this is my first bug report for open source project :-)  

Best regards
Stephan Springer
