3392 /* IFBLOCK jumping algorithm
3393  *
3394  * This is easier as it looks like:
3395  * - each IF checks it's condition
3396  *   - on FALSE: call DO_JUMP
3397  *   - on TRUE: don't care
3398  * - each ELSE calls DO_JUMP unconditionally
3399  * - each ENDIF is silently being ignored
3400  *
3401  * Why this works:
3402  * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target
3403  * (i.e. the corresponding ELSE or ENDIF). After that, processing for the given
3404  * object can continue, free()ing stuff e.g., then the for-loop does the rest: as
3405  * regularly, "obj" is being updated to point to obj->next, so object parsing
3406  * continues right after the corresponding ELSE or ENDIF. This means that if we
3407  * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
3408  * always. If we encounter an ENDIF, it's corresponding IF or ELSE has not
3409  * jumped, and there is nothing to do.
