Callbackify won't callback if the callback is the only argument

[hurrymaplelad]

This prints done as expected:

callbackify(function() {
  return Y.resolve('a');
})(1, function() {
  return console.log('done');
});

while this does not:

callbackify(function() {
  return Y.resolve('a');
})(function() {
  return console.log('done');
});

The only difference is the first example passes an extra (unused) argument to the function returned by callbackify.

Thanks for your report. I have added two test cases for this function. The fixed new version has published.
