yes, they should be but the Engine doesn't add the EXT_STMT opcode into
which Xdebug can hook in at those places. I can overload some other
opcodes to make the code coverage see that those lines are executed, but
then the numerical value will be totally unlogical. I do think this is
the way to go though. I'll keep you posted on the progress.
