Yes, copies create a special pair of properties in SVN: copyfrom_rev and copyfrom_path.  Unfortunately SVN users use the copy operation for non-branching purposes, so some amount of filtering is required.  I posted a script earlier in this thread that used one set of heuristics based on my local SVN repository, but I'm not claiming it will work for everyone.

David just brought up teaching svn-fe to emit the copyfrom properties to help git do branch mapping.  I think there's still a lot of effort in creating a good mapping algorithm, but the pieces are coming together.
