In Git v2.0, we will change the default --prefix for init/clone from none/empty to "origin/" (which causes SVN-tracking branches to be placed at refs/remotes/origin/* instead of refs/remotes/*). This patch warns users about the upcoming change, both in the git-svn manual page, and on stderr when running init/clone in the "multi-mode" without providing a --prefix.
