Defaulting to HTTPS on YouTube

[mmcco]

This is a minor issue, but when you supply a YouTube link without an http:// or https:// prefix, the first output line is:

WARNING: The url doesn't specify the protocol, trying with http

Because HTTPS is default and expected on YouTube these days, it would be nice if youtube-dl defaulted to it.

It seems that a condition or a call to a helper function here is all we would need.

Thanks for your time.

youtube-dl supports not only YouTube, some of which are only accessible by http.

I'm aware of that. It would be extremely simple to check the URL against a list of domains known to support HTTPS, though. That's what I was suggesting.

Note that in the case of YouTube videos the extractor matches http:// urls and it will do all the requests with htttps://, so it won't use any insecure connection.
