Revive svn+http(s) URLs support (issue94) Telling svn from mercurial repository automatically is not always possible, or at least not seamlessly. Let 'http://repo.com/svn' be an svn repository, protected with basic authentication. Trying to clone it directly does something like: 1- Open it like a mercurial repository: * send between command, ask for credentials, fail * fallback to static-http, ask for crendentials two times, fail 2- Open it like an svn repository Mercurial [auth] facility is helpful here, but few people know about it, and it may seem weird to store svn credentials in mercurial configuration. An svn-like password manager would not help either because all connections attempts in [1] fail and it's unlikely we would store credentials in this situation. Instead, we can clone 'svn+http://repo.com/svn', which will skip step [1].
