Windows doesn't like single quotes

Windows doesn't like single quotes to be used as argument "wrappers", it will try to include them literally in the command-line argument.

Example:
write-file

```
var FS = require('fs')
var Path = require('path')

var file = process.argv[2]
FS.writeFileSync(Path.join(__dirname, file), 'foo')
```

When I call `node write-file 'hello.txt'`, it creates literally the file `'hello.txt'`, with quotes.
