For the guarantee to hold true, line->buf[0..line->len] should not
have any '\0' byte in it.  

This helper has two callers, but in either case, it needs to be
prepared to work on output of decode_[bq]_segment().  Is there code
anywhere that guarntees that the decoding won't stuff '\0' in the
line?
