git: c4804b6b0b94 - main - Unbreak TFO, that was broken with 8d5719aa74f. These two assignments are unneccessary and used to be there before TFO as an invariant. With TFO and after 8d5719aa74f the "so" value is still needed.

    Unbreak TFO, that was broken with 8d5719aa74f.  These two assignments
    are unneccessary and used to be there before TFO as an invariant.  With
    TFO and after 8d5719aa74f the "so" value is still needed.
