Since "svn status" is run for every file because of the removed check
for .svn in every directory, don't complain if it fails. The check is
made more robust by adding @ to the file name, for files whose names
contain that character.

* contrib/client-side/emacs/dsvn.el
  (vc-svn-run-status): Append @ to the file name.
  (vc-svn-parse-status): Don't complain on error.
