Proxy server #2
Description
Always the bane of any http based project, I'm behind a corporate firewall and can only access the internet through a proxy server.
I already set the proxy server in Emacs using url-proxy-services, so it might be nice to automatically pick up proxy server settings from it.
I tried working round it myself by adding a "--proxy" flag to plz-curl-default-args, but it fails as curl returns a second set of headers for the proxy server:
> curl.exe --silent --location --dump-header - --proxy http://localhost:3128 "https://httpbin.org/user-agent"
