Thanks for the suggestions, Ken. I have updated them all except for the following:

• I'd like more input on "disallowMultipleLineBreaks": true before removing it.
• Since git takes care of line break normalization, I'd rather not add "validateLineBreaks": "LF".

Some other comments:

• The "disallowSpaceBeforeBinaryOperators": [ ":" ] rule was to get around a bug in jscs which has since been fixed.
• The exact reason I chose escape: true for validateQuoteMarks was for locale strings.

Once the two issues you noted get resolved, I think this config file is good to go.
