GCM ignores NO_PROXY environment variable

[u1735067]

Hello,

I see in https://github.com/microsoft/Git-Credential-Manager-for-Windows/blob/master/Docs/Environment.md honor http_proxy and https_proxy (both upper and lower case it seems), but it completely ignores no_proxy while git honor it.

So git is properly handling requests, but GCM can leaks informations through the proxy while it shouldn't.

Could GCM handle this environment variable the same way gitdoes, which is https://curl.haxx.se/docs/manual.html (§Environment Variables, as per https://github.com/git/git/search?q=no_proxy&unscoped_q=no_proxy)?

Best,
