Re: svnadmin obliterate features

Just in case:

Several Subversion developers are partially offline this week,
attending OSCON in Portland, Oregon, USA. Plenty of developers are
not attending OSCON, of course, but just be aware that some people who
might normally participate in this discussion are unavailable right
now. It's still good to have the discussion -- I just wanted you to
know why the response rate might be lower than usual.
