I think the code should read:

 if( nLeft || nRight ) 
     { 
         if( !pCurr->GetPortion() ) 
             pCurr->SetPortion( new SwTxtPortion( *pCurr ) ); 
         if( nLeft ) 
         { 
             SwMarginPortion *pMarg = new SwMarginPortion( 0 ); 
             pMarg->AddPrtWidth( nLeft ); 
             pMarg->SetPortion( pCurr->GetPortion() ); 
             pCurr->SetPortion( pMarg ); 
         } 
         if( nRight ) 
         { 
            SwMarginPortion *pMarg = new SwMarginPortion( 0 ); 
             pMarg->AddPrtWidth( nRight ); 
             pCurr->FindLastPortion()->Append( pMarg ); 
         } 
    }

Since we have "if( nLeft || nRight )", what about:
 if( nLeft || nRight ) 
     { 
         if( !pCurr->GetPortion() ) 
             pCurr->SetPortion( new SwTxtPortion( *pCurr ) );
       SwMarginPortion *pMarg = new SwMarginPortion( 0 );
         if( nLeft ) 
         { 
             pMarg->AddPrtWidth( nLeft ); 
             pMarg->SetPortion( pCurr->GetPortion() ); 
             pCurr->SetPortion( pMarg ); 
         } 
         if( nRight )
         { 
             pMarg->AddPrtWidth( nRight ); 
             pCurr->FindLastPortion()->Append( pMarg ); 
         } 
    }

If nLeft and nRight are exlusive, it could also just be an if(nLeft)... else...

In both cases, no need to repeat "SwMarginPortion *pMarg = new SwMarginPortion( 0 );" since we're 
sure to be in one of these blocks.
