There are several issues with urllib.request.proxy_bypass_environment: 1. Leading dots are ignored in the proxy list, but not in the checked hostname. So ".localhost" does not matches ".localhost" in the proxy list. 2. A single trailing \n in the checked hostname is ignored, so "localhost\n" passes the check if the proxy list contains "localhost". But "localhost\n\n" and "localhost " do not pass. This is an artifact of using $ in the regular expression.
