- Drag, double-click (word) and triple-click (line) selection in the log, auto-scroll at the edges, soft-wrapped lines joined on copy. - sashidown ANSI renderer: delimiter runs with flanking rules, so intraword underscores (test_apply_patch.c) stay literal; unmatched * _ and backticks are shown as-is; * and _ do not close each other. - tests: test_textsel, test_markdown.
