Uncommon Knowledge - WC_Is_Orig%

WC_Is_Orig% contains WC_Is% as it was before the any changes were made to it at the current prompt. Note that this is not synonymous with the value read in from disk as once a prompt has been changed, that change will be reflected in WC_Is% and WC_Is_Orig% when the prompt is re-entered.
