3457  * - each ENDIF is silently being ignored
3458  *
3459  * Why this works:
3460  * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target
3461  * (i.e. the corresponding ELSE or ENDIF). After that, processing for the given
3462  * object can continue, free()ing stuff e.g., then the for-loop does the rest: as
3463  * regularly, "obj" is being updated to point to obj->next, so object parsing
3464  * continues right after the corresponding ELSE or ENDIF. This means that if we
3465  * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
3466  * always. If we encounter an ENDIF, it's corresponding IF or ELSE has not
