	Problem: Visual block insert on a single line incorrectly triggers two on_lines callbacks - one for the correct line (0-indexed) and another for a non-existent additional line. Solution: Only call changed_lines() in block_insert() when additional lines beyond the first were actually modified (start.lnum < end.lnum).
