3706  * This is easier as it looks like:
3707  * - each IF checks it's condition
3708  *   - on FALSE: call DO_JUMP
3709  *   - on TRUE: don't care
3710  * - each ELSE calls DO_JUMP unconditionally
3711  * - each ENDIF is silently being ignored
3712  *
3713  * Why this works:
3714  * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target
3715  * (i.e. the corresponding ELSE or ENDIF). After that, processing for the given
3716  * object can continue, free()ing stuff e.g., then the for-loop does the rest: as
3717  * regularly, "obj" is being updated to point to obj->next, so object parsing
3718  * continues right after the corresponding ELSE or ENDIF. This means that if we
3719  * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
3720  * always. If we encounter an ENDIF, it's corresponding IF or ELSE has not
3721  * jumped, and there is nothing to do.
