Prevent String#split from throwing away empty trailing elements
The default behavior of String#split will throw away any trailing values if they are empty.
> "Hello,There,,".split(',')
=> ["Hello", "There"]
If you want to keep those empty trailing elements, pass a negative number for the second (limit) parameter.
> "Hello,There,,".split(',', -1)
=> ["Hello", "There", "", ""]
