NodeSet#slice doesn't handle ranges beyond the end of the array

[gpherguson]

Looks like NodeSet#slice isn't handling range beyond the end of the array...

#!/usr/bin/env ruby

require 'rubygems'
require 'nokogiri'

xml = Nokogiri::XML('<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
   <channel>
    <item><title>t1</title></item>
    <item><title>t2</title></item>
   </channel>
</rss>
')
items = (xml/:item)
not_blowed_up = items[0, items.size]
all_blowed_up = items[0, 100]
