 when he inserts an obfsuscated `Bridge` line in a torrc without a
 corresponding `ClientTransportPlugin` line? I thought the user was only
 supposed to get the weird "We were supposed to connect to bridge..."
 > Oh hm, I guess I screwed that up. When I first tested this, I added
 'bridge obfs3 x.x.x.x:y' and I got "[Warning] Error parsing Bridge address
 'obfs3'" followed by "[Warning] Controller gave us config lines that
 didn't validate: Bridge line did not parse. See logs for details."
 > However, when I added 'obfs3 x.x.x.x:y' I received "We were supposed to
 connect to bridge 'x.x.x.x:y' using pluggable transport 'obfs3', but we
 can't find a pluggable transport proxy supporting 'obfs3'. This can happen
 if you haven't provided a ClientTransportPlugin line, or if your pluggable
 transport proxy stopped running."

 I assume that users run into the first error more frequently than the
 second (i.e. they add "bridge obfs3 ...." to Vidalia because that's what
 bridges.tpo says they should do). If users should add "obfs3 ..." without
 "bridge" in front of it, then we need to specify that on the page - or
 stop giving out bridges in that format.
