It seems fair to dislike YAML (I dislike it too), but I don't understand how this broke for you unless CircleCI (or whoever) isn't actually using a legal YAML parser.

    irb(main):009:0> YAML.load <<EOD
    irb(main):010:0" key:
    irb(main):011:0"  - value 1
    irb(main):012:0"  - value 2
    irb(main):013:0" EOD
    => {"key"=>["value 1", "value 2"]}
    irb(main):014:0> YAML.load <<EOD
    irb(main):015:0" key:
    irb(main):016:0" - value 1
    irb(main):017:0" - value 2
    irb(main):018:0" EOD
    => {"key"=>["value 1", "value 2"]}

(This works for any number of leading spaces, so long as the spacing is consistent.)
