Overwrite of $edit['multiblock_delta']

In the following code in multiblock.module (lines 76-96):

function multiblock_call_block($delta, $op, $edit) {
  $result = db_query("SELECT module, orig_delta, delta, multi_settings FROM {multiblock} WHERE delta='%s'", $delta);
  if ($block_info = db_fetch_object($result)) {
    // If this block is multiblock enabled, send it the delta of the block we're using.
    if ($block_info->multi_settings == 1 ) {
      $edit['multiblock_delta'] = array(
        '#type' => 'value',
        '#value' => $block_info->delta,
        );
    }

    $edit['multiblock_delta'] = $delta;

    $block = module_invoke($block_info->module, 'block', $op, $block_info->orig_delta, $edit);
//    if ($op == 'view') {
//      $block['orig_module'] = $block_info->module;
//      $block['orig_delta'] = $block_info->orig_delta;
//    }
    return $block;
  }
  // No such multiblock, shouldn't ever happen.
  return;
}

line 86 ($edit['multiblock_delta'] = $delta;) overwrites possible result of the conditional statement right above.
Delta for multiblock-enabled blocks is then not taken from multiblock table.
This also forces the delta to be retrieved using $edit['multiblock_delta'] and not $edit['multiblock_delta']['#value'] as it used to be in the previous release therefore making this version of the module not back compatible.
