Support sudo without -E

[schlamar]

Proxy settings are lost when using sudo without the -E flag:

$ echo $http_proxy
http://.../
$ sudo su
# echo $http_proxy

#

The solution is to add the variables to the env_keep sudo settting. Just create a file with owner root and mode 0440 as /etc/sudoers.d/proxy with the content:

Defaults env_keep += "http_proxy https_proxy ftp_proxy no_proxy"

Yet another great idea. Thanks Marc! 👍
Worth a note that some old distros don't have sudoers.d enabled by default, but luckily they are slowly vanishing.

I'll definitely implement this. But I plan to cut a release first for #21 today.
