=begin
 for ruby in ~/.rbenv/versions/{1.9.3-p327,2.0.0-p0}/bin/ruby
 do
   "$ruby" -v
   "$ruby" -e 'p /x.*?\Z$/ =~ "x\ny"'
 done

:In Ruby 1.9: (({nil}))
:In Ruby 2.0: (({0}))

If you remove the "y" from the string, or add more, then they do the same thing.
The temporary solution I'm using to get around this is to replace `(({\Z}))` with `(({\n\z}))`
