YAML can't round-trip the hash: {"default"=3D>"\r\n  Monkey \r\nX"}.

Shouldn't yaml use the escaped string format for any string that starts wit=
h whitespace, ie,

yaml =3D "--- \ndefault: \"\\r\\n  Monkey \\r\\nX\""
p YAML.load(yaml)
=3D> {"default"=3D>"\r\n  Monkey \r\nX"}

Below is a demonstration of this:

ruby <<-EOF
hash =3D {"default"=3D>"\r\n  Monkey \r\nX"}
yaml =3D YAML.dump(hash)
p yaml
hash2 =3D YAML.load(yaml)
EOF
"--- \ndefault: |-\n  \r\n    Monkey\r\n  \r\n  <h2>Contact us</h2>\n"

Same bug exists in the jruby implementation as well.
