// and analyze stdout to build a rouille response.
//
// Note that an error is returned only if `git http-backend` fails to execute, and not
// if the client sends bad data for example. In other words, an error can only occur
// if the server was misconfigured. Therefore it's okay-ish to call `unwrap()` here.
