Yeah, I thought so, somehow I just didn't have the idea to look at
debugv() when you mentioned the problem.

Well, I tried doing that with the signature-log backend, but that seemed
somewhat problematic to me although somebody said it actually works for

Thanks, I've added the Makefile patch, but the other one I'm not too
sure about, it seems it would print things twice if the loop actually
looped, so I left it for now. Also, your code can access
buf[sizeof(buf)] which would be a buffer overrun.
