example does not output valid yaml.

[Aricg]

Code:

    yaml_cli \
    -n andy:test:number 5 \
    -b andy:test:bolean_value true \
    -s andy:test:a_string 'Text with whitespaces' \
    -l andy:test:basic_list_support item1 and2 and3 \
    --null andy:test:null_value

Output:

andy:
  test:
    a_string: Text with whitespaces
    basic_list_support:
    - item1
    - and2
    - and3
    bolean_value: true
    null_value: null
    number: 5

The list items need to be further indented to be valid yaml.
