I suspect for consistency, using https:// is the way to go.

I'm a bit sad to see "git:" go, since that was visually such a good
marker that it's about a _git_ server, not some random web page (and I
rely on the signed tag, not on some https thing).

But from a technical angle, I guess it was inevitable. And git is
everywhere, and 'github' certainly makes that "it's a git repo" part
obvious anyway, so.
