I find that you can access older revisions via web browser by using URLs
like this:
https://server/svn/!svn/bc/123 where 123 is the revision number you seek.
I'm not sure why this isn't documented in the SVN book. According to
the DelvtaV standard, the URL syntax used to differentiate between
versions is left up to the server, and the client needs to use special
requests to ask the server what URL to use to access specific versions.
I looked at apache's access log though and found that svn was using
URLs like the above, and gave it a try and it worked.
