The problem is that syntax highlighting of code blocks happens at an 
earlier stage according to the spec (see "Phases of Processing" at 
http://dlang.org/spec/ddoc.html).

I just checked and I'm actually doing it the other way around in DDOX, 
without encountering different results so far, so it may be realistic to 
change this for Ddoc, too.
