Hello Berry,

according to the history of lisp/vc/vc-svn.el in the GNU Emacs 24 Bazaar branch (http://bzr.savannah.gnu.org/r/emacs/emacs-24), a first version of that file was committed on 2003-05-05. In r103228 on 2011-02-11, support for Subversion 1.7's new only-one-.svn-dir working copy format was implemented. The current GNU Emacs version 24.3 has no problems dealing with Subversion 1.7 or 1.8 working copies right out of the box :-).

You're probably not the last person on the planet using Emacs 21... yet. Come over to the 24-side... we have cookies! :-D

Have a nice weekend,
