Fix to SafeRange to allow more valid ranges
Fix to SafeRange to allow more valid ranges

The expression startIndex + endIndex > len is not needed.
The fix will allow the following ranges to be valid:
- n to Array.length, n = {1, 2, ..., Array.length-1}
- n to m, n = {1, 2, ..., Array.length - 1}, m = {n+1, ..., Array.length}
