         We'd like to use the notifier, but we MAY have a couple of
         problems with that, the same problems that used to apply to
         the old trace_editor:
         
         1) We don't know where the commit editor for this case will
            be anchored with respect to the repository, so we can't
            use the DST_URL.

         2) While we do know where the commit editor will be driven
            from with respect to our working copy, we don't know what
            basenames will be chosen for our committed things.  So a
            copy of dir1/foo.c to http://.../dir2/foo-copy-c would
            display like: "Adding   dir1/foo-copy.c", which could be a
            bogus path.
