[Bug 43783] Office2013 activation crashes when using HTTP proxy

--- Comment #26 from Luiz Angelo Daros De Luca  ---
I unset all *_proxy vars (do a 'set | grep -i proxy'). Normally you need to
unset only http(s)_proxy. I use this to unset them for a single call

env {http,https}_proxy= wine myapp.exe

Which is equivalent to

http_proxy= https_proxy= wine myapp.exe

But you can unset with export too.
