I googled for that but didn't find any info, anyway if that's true did they 
do this by 1) removing http_proxy from environment or by 2) patching
libcurl not to read them ? if it's the first case, we are safe as they will 
also remove the vars and we won't read them, if it's second case, it's silly
on their part as any other console program will be reading env vars as they
would need to patch every program..

The normal thing os's do (as gnome used to do) is to automatically set the
http_proxy env vars when you set a proxy on the GUI..
