Growing file with |+ syntax

[Wolf2323]

when saving and loading a file like this:

# YAML load and save bug with keep block chomping indicator
example:
  description: |+
    These lines have a carrage return after them.
    And the carrage return will be duplicated with each save if the
    block chomping indicator + is used. ("keep": keep the line feed, keep trailing blank lines.)

successfully-loaded: test 

The empty line after the text related to |+ is duplicated every load and save.

@Wolf2323 I added the test and look perfect: https://bitbucket.org/snakeyaml/snakeyaml/src/master/src/test/java/org/yaml/snakeyaml/issues/issue520/ChompingTest.java

Can you please provide a failing test ?
