fixed array escaping

[dloose]

I noticed the arrays don't get escaped properly if you have an escape function. The wrapQuotes function does map over the elements of the array, so something like [1, 2, 3] becomes "(1, 2, 3)". Then the the escape function was applied to the result string, yielding something like '\"(1, 2, 3)\"'. I munged together a solution that works in my limited testing. Not saying it's the best way to do it, but hopefully it helps illustrate the problem.
