Repeat doxygen comments in pvAlarm.h

[thomasms]

While trying to understand the pvData API I came across a duplicate doxygen comment in the PVAlarm header file.

    //default constructors and destructor are OK
    //returns (false,true) if pvField(is not, is) a valid alarm structure
    //An automatic detach is issued if already attached.
    /*
     * Attach to a field of a PVData object.
     * @param pvField The pvField.
     * @return (false,true) if the pvField (is not, is) an alarm structure.
     */
    /*
     * Attach to a field of a PVData object.
     * @param pvField The pvField.
     * @return (false,true) if the pvField (is not, is) an alarm structure.
     */
    bool attach(PVFieldPtr const & pvField);

Small issue I know, but I thought worth mentioning.
