travis: whitespace-only changes for consistency

Automatically apply a consistent indentation with:

    python3 -c 'from ruamel.yaml import YAML;y=YAML();d=y.load(open(".travis.yml"));y.width=500;y.dump(d,open(".travis.yml.new","w"))'

followed by manually re-indenting three comments.

Closes #5370
