Inconsistent parsing in CRuby vs JRuby

[lephyrius]

I tested this is IRB:

1.9.3p286 :002 > require 'nokogiri'
 => true 
1.9.3p286 :003 > Nokogiri::HTML::DocumentFragment.parse("")
 => #<Nokogiri::HTML::DocumentFragment:0x80829828 name="#document-fragment"> 
1.9.3p286 :004 > Nokogiri::HTML::DocumentFragment.parse(" ")
 => #<Nokogiri::HTML::DocumentFragment:0x80434038 name="#document-fragment"> 

jruby-1.7.0 :001 > require 'nokogiri'
 => true 
jruby-1.7.0 :002 > Nokogiri::HTML::DocumentFragment.parse("")
 => #<Nokogiri::HTML::DocumentFragment:0x7fa name="#document-fragment"> 
jruby-1.7.0 :003 > Nokogiri::HTML::DocumentFragment.parse(" ")
 => #<Nokogiri::HTML::DocumentFragment:0x7fe name="#document-fragment" children=[#<Nokogiri::XML::Text:0x7fc " ">]> 

As you can see. JRuby got children.

This appears to be a dupe of #847 (or that is a dupe of this). In any case, it's not clear to me what the real-world impact of this is, and so I'm closing.

I'm happy to reconsider if you'll help me understand what affect this behavior is having.
