3055  * This is easier as it looks like:
3056  * - each IF checks it's condition
3057  *   - on FALSE: call DO_JUMP
3058  *   - on TRUE: don't care
3059  * - each ELSE calls DO_JUMP unconditionally
3060  * - each ENDIF is silently being ignored
3061  *
3062  * Why this works:
3063  * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target
3064  * (i.e. the corresponding ELSE or ENDIF). After that, processing for the given
3065  * object can continue, free()ing stuff e.g., then the for-loop does the rest: as
3066  * regularly, "obj" is being updated to point to obj->next, so object parsing
3067  * continues right after the corresponding ELSE or ENDIF. This means that if we
3068  * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
3069  * always. If we encounter an ENDIF, it's corresponding IF or ELSE has not
3070  * jumped, and there is nothing to do.
