------- Additional Comments from Benjamin Poulain <benjamin at webkit.org>
Looks like I have addressed the two mistakes, so let's put this version for
review.

Something to be careful when reviewing:
stringBuilder::toString() return String::empty(). Previously, some functions
would have returned a null string instead of an empty string.

I think I got them covered but I may have missed something so a careful review
would be appreciated.
