ini_inv_mkobj_filter() bit

The try count of 1000 is never going to be reached.

The obj result, if it were ever to be reached, would have
been unfiltered and potentially incorrect.

There is no harm in having the result, in that theoretical edge
case, not be one of the obj values that was intended to be
filtered out.

No practical change results from this, and pancake was used
because it is innocuous.
