     * at least one "x" bit before, and for directories.
     * This emulates the behavior of chmod +X.

     * @param lstItems The file items representing several files or directories.
     * @param permissions the permissions we want to set
     * @param mask the bits we are allowed to change.
     * For instance, if mask is 0077, we don't change
     * the "user" bits, only "group" and "others".
