Slice ranges were not correctly determined for negative indices and also off by one in general (included one more element at the end of the substring than what actually matched the index range). It's now equivalent to Python slice notation. Accessing a string at a single index is also the same as Python except that an out-of-range index returns an empty string instead of throwing an expection.
