Comment 1 for bug 303422

Fixed with this commit in svn trunk, but I don't want to risk this change in the 1.8 branch:

2008-12-04 Murray Cumming <email address hidden>

 * glom/libglom/data_structure/foundset.[h|cc]: Added has_no_criteria()
 to check if it has a sort order or where clause.
 * glom/libglom/document/document_glom.[h|cc]: Added
 set_criteria_current(), like set_layout_current(), so we can
 temporarily remember the sort (and find) for a table while navigating.
 DocumentTableInfo: Hand-wrote copy constructor and operator=() rather
 than depend on generated ones.
 * glom/utility_widgets/db_adddel/db_adddel.[h|cc]:
 Added signal_sort_clause_changed, emitted when the user clicks on
 the column header, which already caused a refresh with that sort.
 * glom/mode_data/box_data_list.[h|cc]: Respond to a sort change in the
 DbAddDel widget, saving it temporarily in the document.
 * glom/mode_data/frame_glom.cc: show_table(): Use the remembered
 criteria, from the document, where there is one.
