urllib2 already knows about this syntax for proxy auth (ProxyHandler.proxy_open). If somebody fixes this (assuming it needs fixing -- I haven't read what the standards say), note that the Basic authentication logic is duplicated, and perhaps broken in one place, which should probably be fixed at the same time:

If nobody does it first, I'll fix it eventually (I'm lazy about configuring a local proxy and web server...).

BTW, is somebody planning a 2.3.4 (or 2.2.4)? When? That would motivate me to fix urllib2 bugs sooner.
