The disabling of shell proxies didn't work for me recently.

Instead of setting the variables to empty, I think we need to use 'unset'.

i.e.

unset http_proxy
unset https_proxy
unset HTTP_PROXY
unset HTTPS_PROXY

export / unset depends upon the shell youre using. I'm on the iterm2 default and export worked but unset didn't.

Unusually, in my case (I'm using zsh btw) setting the variables to empty doesn't work though, so we maybe need something else.
