No. It is more an assignment and not a +. Remember replaces any existing 
history.

History is a container of strings, so you can use whatever formater you 
want. dumpRange is the most flexible we have, but if you're happy with

    /** The history as string. Empty if \ref historyEmpty.
     * Otherwise:
     * \code
     * History:
     *  - most recent message
     *  - 2nd message
     * ...
     *  - oldest message
     * \endcode
    */
    std::string historyAsString() const;


So: ERR << error << endl << error.historyAsString();
