sslutil: handle default CA certificate loading on Windows See the inline comment for what's going on here. There is magic built into the "ssl" module that ships with modern CPython that knows how to load the system CA certificates on Windows. Since we're not shipping a CA bundle with Mercurial, if we're running on legacy CPython there's nothing we can do to load CAs on Windows, so it makes sense to print a warning. I don't anticipate many people will see this warning because the official (presumed popular) Mercurial distributions on Windows bundle Python and should be distributing a modern Python capable of loading system CA certs.
