CHOP key count Removes characters from a value to a String key. If 'count' is positive or zero, it removes from the right of the string; if 'count' is negative, it removes from the left of the string. If |count| is greater than the string length, the value is set as an empty string. It is an error if the value is not a String. Integer Reply: the length of the string after the chop operation.
Since Redis 4 was released without redis/redis#3718 this change was required to make CHOP work properly with Redis 4.0.0. Now all tests pass on stock Redis 4.0.0.
Includes test and documentation.
