// to catch cases where someone called us with a negative 'nchars' value - in those
// cases we'll just throw a 'INDEX_SIZE_ERR' (acid3 implicitly agrees with us)
//
// #2: We only throw if 'charnum + nchars' is greater than the number of characters, not
// if it's equal, as this really doesn't make any sense (no way to measure the last character!)
//
// #3: If 'charnum' is greater than or equal to 'numberOfChars', we're throwing an exception here
// as the result is undefined for every other value of 'nchars' than '0'.
