I don't think we want to mess with existing remote refs without the user's consent, especially since the user might have all kinds of repo-specific practices tied to the old layout of remote refs.

Providing a command to do it (git remote renew?) is a much better way to go about it, IMHO. Still, it is vitally important that new git keeps working with old-style remotes.

Another issue is whether we should automatically make the old-style implicit refspecs into _explicit_ (but still old-style) refspecs. I.e. when encountering an old-style remote, new git could automatically add the following refspecs to the remote:

	+HEAD:refs/remotes/origin/HEAD
    ~refs/tags/*:refs/tags/*
