Draw the TreeView debugging graphs using unicode box-drawing characters. (Closed-Leaf check-in: 0efc6859d1 user: drh tags: box-character-graph)
19:04
Improvements to the new syntax-tree output routines: Omit the "END SELECT" mark and instead terminate the graph at the last item. Increase the maximum tree depth to 100. (check-in: 5ce05757aa user: drh tags: trunk)
