So I have gotten around to looking at this and I have a few questions.
When pasting code it appears to default to
which I assume is for the google prettify module. The problem is that I have not got that module switched on, so therefore should not be added to me pre class at all.I blogged about this problem, where modules are switched off and yet still run on the interceptors as being a potential problem. This is a perfect example of this being a problem, well not a problem really but it should not be there if the module is switched off.
