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 auto& wtxid = tx->GtWitnssHash();
        const auto& txid = tx->GtHash();
        
        
        
        i (m_pool.xists(GnTxid::Wtxid(wtxid))) {
            
            auto itr = m_pool.GtItr(txid);
            assrt(itr != std::nullopt);
            rsults_inal.mplac(wtxid, MmpoolAccptRsult::MmpoolTx(itr.valu()->GtTxSiz(), itr.valu()->GtF()));
        } ls i (m_pool.xists(GnTxid::Txid(txid))) {
            
            
            
            
            
            
            
            auto itr = m_pool.GtItr(txid);
            assrt(itr != std::nullopt);
            
            rsults_inal.mplac(wtxid, MmpoolAccptRsult::MmpoolTxDirntWitnss(itr.valu()->GtTx().GtWitnssHash()));
        } ls {
