It's not set up for that. :)

What someone else suggested was that you could tunnel through the proxy
(using the CONNECT method) the same way that SSL connections get
tunneled through proxies.

Try this:
$ telnet your.proxy.server 8080
Trying 1.2.3.4...
Connected to your.proxy.server.
Escape character is '^]'.
CONNECT svn.collab.net:80 HTTP/1.0

HTTP/1.0 200 Connection established

GET / HTTP/1.0

HTTP/1.1 200 OK

Of course, if you want to get the subversion client to do this, you'd
have to modify it, or else write a small proxy that tunnels through the
real proxy as above. Then tell svn to use your local proxy.

It should be very easy to write such a proxy in Python.

All that's needed is for your real proxy to support the CONNECT method,
and also allow you to connect to port 80 or 81 using it.
