Syntax conversion does not treat escaped syntax characters correctly.

Syntax conversion does not treat escaped syntax characters correctly, for example;

Create an XWiki 1.0 syntaxc page with this text;

Here are some \[square brackets\]

Now change the syntaxId to 2.0 and hit ok to produce the following text;

Here are some \[[square brackets\]]

Now try to save or preview, and it fails and throws

Exception: String index out of range

I think the Exception is thrown in the course executing org.xwiki.rendering.block.AbstractFatherBlock.traverse() and it is trying to treat the text as a

org.xwiki.rendering.block.LinkBlock

with the actual exception being thrown in

org.xwiki.rendering.internal.renderer.DefaultLinkLabelGenerator.generate()

at line 59.
