fs.mkdir / fs.mkdirSync - mode parameter

[Bonuspunkt]

mode is ignored on windows, so it should be a optional parameter / have a default value

>node -v
v0.5.10

>node --eval "require('fs').mkdirSync('newDir')"

fs.js:361
  return binding.mkdir(path, modeNum(mode));
                 ^
TypeError: Bad argument
