/* ### TODO:  Multiple Targets

    - Up for debate:  an update on multiple targets is *not* atomic.
    Right now, svn_client_update only takes one path.  What's
    debatable is whether this should ever change.  On the one hand,
    it's kind of losing to have the client application loop over
    targets and call svn_client_update() on each one;  each call to
    update initializes a whole new repository session (network
    overhead, etc.)  On the other hand, it's a very simple
    implementation, and allows for the possibility that different
    targets may come from different repositories.  */
