Executive summary: If the indices here are used as [fromIndex toIndex) --
that is, inclusive-exclusive -- as is often the custom, *and* a
zero-length range is permitted, then this code is correct as written.
Plus, if this was a commonly-used code fragment, any error would have
turned up long ago.
Finally, the keyword "private" means that this function is unavailable
outside of the file that defines it. There would be no reason to document
it. There would also be no reason to hold it to any standard other than
that it perform the specific function for which it was intended. Without
seeing the functions or methods that call it, there's really no true way
to know if it's buggy or not.
