Then I'm not sure what you did mean.

Perhaps. However

$ svn list ^/subversion/branches ../src/COMMITTERS

appears to use it just find a repository, and

$ svn merge ^/foo ^/bar wc

behaves in almost exactly the way I would like diff to behave. I
agree it does use the wc path beyond merely constructing URLs, but the
way it constructs URLs is the way I would like diff to behave.
