discovered dead code in SVG stylesheet title handling of "&"

[Darin Adler]

In Document::recalcStyleSelector I discovered some dead code that I removed:

#if ENABLE(SVG)
                // FIXME: What's the point of changing the value of a local variable
                // (title) that's not looked at afterward? Obviously there's no test
                // case for this!
                if (!n->isHTMLElement()) {
                    String modifiedTitle = title.domString();
                    title = modifiedTitle.replace('&', "&&");
                }
#endif

We should figure out what this code was trying to do, and then possibly re-add the code with a test case.

In practice this never turned out to be a problem - closing this bug.
