includeStackTrace option doesn't seem to cause any effect

[jhenriquez]

I'm trying to override the includeStackTrace default which I assume has the same effect as the --noStack argument. For some reason setting it doesn't seem to have any effect. I see jasmine-node is using the option: https://github.com/mhevery/jasmine-node/blob/master/lib/jasmine-node/index.js#L95

I'm new to grunt, am I misunderstanding the proper way to configure the task?

jasmine_node: {
  options: {
    includeStackTrace: false
  },
  all: ['spec/']
}
