Summary:  Incorrect example for strings in flash

Original Submission:  The code in the FAQ entry "How do I put an array of 
strings completely in ROM?" is incorrect. Array elements are not read the right 
way (note that the array of pointers resides in flash).

Here is a working solution. Instead of:
//------------------------------------
        strcpy_P (buf, array[1]);
//------------------------------------

Should be:
//------------------------------------
        PGM_P p;
        memcpy_P( &p, &array[1], sizeof(PGM_P));
        strcpy_P (buf, p);
//------------------------------------
