s-l-r does not pass along http_proxy and https_proxy values for git
I like s-l-r very much, but I have a problem using it behind a proxy firewall. Any repository served up by git always fails with a non-zero return value because the repository is unreachable. This is because the proxy settings are not passed along. If I modify the git_2.py code to declare http_proxy and https_proxy on the command line, then everything works as expected.
