Another (different, I think) roundtripping failure related to collapsing newlines is:

 orig = "hoge\n\nhoge"
 def orig.to_yaml_style ; :fold ; end
 new = YAML.load(YAML.dump(orig))
 puts "Should be #{orig.inspect}, but is: #{new.inspect}"
 puts "YAML: #{YAML.dump(orig).inspect}"

Which yields:

 Should be "hoge\n\nhoge", but is: "hoge\nhoge"
 YAML: "--- >-\nhoge\n\nhoge\n"

It's present in ruby_1_8 as of last week, at least.
