Added spec to check some indents.

NOTE: "rake" fails currently until after PR#1201 merger.

Isn't this something that yamllint should be handling? I thought it was previously checking indentation?

[jasnow]

Try this:

yamllint $(find gems rubies -type f )

[jamgregory]

yamllint is configured to use consistent indentation (https://yamllint.readthedocs.io/en/stable/rules.html#module-yamllint.rules.indentation) which only means they need to be consistent (which Psych is correctly generating) but that doesn't appear to be the correct rule - it needs updating to true as that will ensure it is indented according to the repo's guidelines
