condenseFlow in combination with flowLevel 0 is broken

[arabold]

Simple sample code:

var jsYaml = require("js-yaml")
console.log(jsYaml.safeDump({ a: "a", b: "b", c: "c" }, { flowLevel: 0, condenseFlow: true }))

This results in a broken string like this:

{"a":a", b":b", c":c}\n

Without condense flow the result works as expected:

{a: a, b: b, c: c}\n

Those params should not be combined together. If one wish to use both - that's not our client :)
