     * 5.2.3.  Merge Paths
     *
     *    The pseudocode above refers to a "merge" routine for merging a
     *    relative-path reference with the path of the base URI.  This is
     *    accomplished as follows:
     *
     *    o  If the base URI has a defined authority component and an empty
     *       path, then return a string consisting of "/" concatenated with the
     *       reference's path; otherwise,
     *    o  return a string consisting of the reference's path component
     *       appended to all but the last segment of the base URI's path (i.e.,
     *       excluding any characters after the right-most "/" in the base URI
     *       path, or excluding the entire base URI path if it does not contain
     *       any "/" characters).
     *
     * @param hasAuthority
