Yet another falsely value issue.

[Frederico Caldeira Knabben]

It's a matter of coding style. Whenever possible, we should code it just like we would usually say it in spoken language: "if the type of data is different from string". So, you end up with if ( typeof data != 'string' ). That's the way you'll find it in our code.

If possible, just fix it when committing.
