Mainline was rewritten to be at least moderately sane so I can
quite believe it is fine.

3.0.4 passing is just a fluke I guess, as it's the same as 3.2.

I'm not sure I can find the willpower to fix this, as there are so
many buffer overflows in tradcpp.c that if I fix one you'd easily
trigger another, and the code is really hard to understand and modify.
