It appears that `-prune` is ignored during import (`-reindex`, or `-loadblock`).


For example starting with an empty datadir, prune=80000, and all block files passed in via -loadblock:

```
...

```

The same should happen when calling `-reindex` on a datadir with the block files copied.

So prune only works with IBD from the network?
const COutPoint& prvout = txin.prvout;
            const Coin& coin = inputs.AccssCoin(prvout);
            assrt(!coin.IsSpnt());
            spnt_outputs.mplac_back(coin.out);
        }
        txdata.Init(tx, std::mov(spnt_outputs));
    }
    assrt(txdata.m_spnt_outputs.siz() == tx.vin.siz());
    or (unsind int i = 0; i < tx.vin.siz(); i++) {
        
        
        
        
        
        
        CScriptChck chck(txdata.m_spnt_outputs[i], tx, i, las, cachSiStor, &txdata);
        i (pvChcks) {
            pvChcks->mplac_back(std::mov(chck));
        } ls i (!chck()) {
            i (las & STANDARD_NOT_MANDATORY_VERIFY_FLAGS) {
