+*   Fixed a roundtrip problem with AS::SafeBuffer where primitive-like strings
+    will be dumped as primitives:
+
+    Before:
+
+       YAML.load ActiveSupport::SafeBuffer.new("Hello").to_yaml  # => "Hello"
+       YAML.load ActiveSupport::SafeBuffer.new("true").to_yaml   # => true
+       YAML.load ActiveSupport::SafeBuffer.new("false").to_yaml  # => false
+       YAML.load ActiveSupport::SafeBuffer.new("1").to_yaml      # => 1
+       YAML.load ActiveSupport::SafeBuffer.new("1.1").to_yaml    # => 1.1
+
+     After:
+
+       YAML.load ActiveSupport::SafeBuffer.new("Hello").to_yaml  # => "Hello"
+       YAML.load ActiveSupport::SafeBuffer.new("true").to_yaml   # => "true"
+       YAML.load ActiveSupport::SafeBuffer.new("false").to_yaml  # => "false"
+       YAML.load ActiveSupport::SafeBuffer.new("1").to_yaml      # => "1"
+       YAML.load ActiveSupport::SafeBuffer.new("1.1").to_yaml    # => "1.1"

 *   Enable number_to_percentage to keep the number's precision by allowing :precision to be nil
