I think I did not change the previous 'while' logic.
It said:
    while ( diff < 0 )

Now it says:
    while ( 1 ) {
        if ( diff >= 0 )
            break;

Previously, the while could be left for a next_dec of 0.
But I agree with you: it could be changed.
Why leaving the loop just to set the decrementer to 0!?
