galvatron.watch doesn't accept an array of strings as second argument

[zephor]

example in the documentation has this line:

galv.watch('src/**', ['dist']);

which has an array of strings as the second argument.

It looks like galvatron.watch only accepts a function as the second arguments:

module.exports = function (pattern, task) {
  var stream = task();

When I try to use the example in the docs I get this error:

TypeError: object is not a function
    at Object.module.exports [as watch] (<project>/node_modules/galvatron/src/watch.js:6:16)
...

either the docs are wrong or this is a bug in galvatron watch?
