* change how the parser should have behaved when parsing content
* up to the point where isELIgnored was set. Arghh!
* Previous attempts to hack around this have only provided partial
* solutions. We now use two passes to parse the translation unit.
* The first just parses the directives and the second parses the
* whole translation unit once we know how isELIgnored has been set.
* TODO There are some possible optimisations of this process.
