[issue42627] urllib.request.getproxies() misparses Windows registry proxy settings

I make some black box tests with the HTTPS proxy. 
Set system proxy `http=https://host:port` and start a HTTPS proxy, then IE, Edge (Chromium) and benrg's code (using `urllib3`) work fine while fetching `http://website`. Then I shutdown the HTTPS proxy and start a HTTP proxy on the same port, I get SSLError. That's it.

benrg should add your patch as soon as possible.
Too few people actually use HTTPS proxy. Even if there is a bug with HTTPS proxy, it will not be too late to fix it when it is discovered.
