Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

npm config list shows all proxy settings except environment variables like HTTP_PROXY, NOPROXY, etc

Expected Behavior

Setting HTTP_PROXY, HTTPS_PROXY or NOPROXY will affect how run npm runs, having these show in npm config list will help users actually see what settings their environment has and prevent easy mistakes.

The expected behaviour would be that an empty npm config list shouldn't use any proxies, or rather, all proxy settings used by npm should be listed.
