Possible regression in git-http-backend

This was the only place I could find this discussed online for uwsgi (but I did find several blog posts comments mentioning the issue).

Here is a gist for providing a config setup, I used the latest nginx from the nginx repo for centos 7 and uwsgi 2.0.14 from epel. The setup requires starting nginx.service and uwsgi.service and creating a bare repo in /srv/git/ and running
