The vc-svn.el file at http://svn.apache.org/repos/asf/subversion/trunk/contrib/client-side/emacs/vc-svn.el for svn support in Emacs 21 broke with the change in Subversion that puts .svn only at the top level of a repository. Now the (vc-svn-registered) test for whether a file is in a Subversion repository always fails, leading Emacs to report that nothing in svn is "under version control".
I made the following trivial change to have that function merely call svn status, omitting the efficiency check for .svn/entries, and it has been working ok. Not sure if vc-svn.el is maintained here or if anyone besides me on the planet is still using Emacs 21, but thought I'd pass it along. If it's deemed worth submitting as an issue, I'm happy to do that.
