Oops :-(.

I have no objection to this thread being here, but please don't start
it as a reply to an unrelated thread. Note this is not merely a
matter of changing the Subject header. See

   http://subversion.tigris.org/mailing-list-guidelines.html#fresh-post

for details.

At this early stage, I would recommend restarting the thread.

Thanks,
