So it would be a bit of work to move this code to using the validate 
framework (that would set a needs_cprotect boolean property to text 
insets). I suspect that now is not the right time to do it, since it can 
wait and we do not want to destabilize current code. But this code 
definitely needs some love.

And all the explicit test of inset codes should go.

Jürgen, can you tell me what is the purpose of the test against math insets?

Do we have a cprotect torture test, BTW?
