Code

  // Query parameters are added in
  // core/includes/pager.inc in the template_preprocess_pager(),
  // where pager_query_add_page() calls pager_get_query_parameters(),
  // which will pick up the ajax wrapper format from the ajax request, which breaks
  // the pager.
  // Unfortunately there is no way to remove this parameter before it is rendered to text,
  // so this preprocess function removes the parameter with string replacement.
  // Remove ajax wrapper format from first, previous.
