"travis compile" includes arrays instead of individual values

[nex3]

If I run travis compile on the following .travis.yml:

language: ruby
rvm:
  - 2.0.0
  - 2.3.0

I get invalid Bash output that includes:

export TRAVIS_RUBY_VERSION=["2.0.0", "2.3.0"]

and

travis_cmd rvm\ use\ \[\"2.0.0\",\ \"2.3.0\"\]\ --install\ --binary\ --fuzzy --assert --echo --timing

I understand that the generated output can't encompass all possible combinations, but silently generating invalid output doesn't seem like the best way of handling it. I'd like a way to select which combination gets generated, and for travis compile to either prompt for a selection or fail if it can't generate valid output.
