Update: initialize string locations to {1, 0}

This is done so that the start position is always after the stop position.
In such a case, this means that the range is undefined.
Originally. -1 was used, but that does not work if the position integers are unsigned.
Using {1, 0} allows for assigning an undefined state with unsigned integers.

Also note that the default of {0, 0} means start at 0 and stop at 0, which would return the value at position 0 and no other values after that first value.
