Fix up merged PRs: land-r6's changes fitted to the landing branch

- review.thesaurus's params doc parses under describe's grammar; describe's edit.copy test
  expects the landing branch's {text, html?} answer.
- The Language dialog test picks the landing branch's "Français (France)" entry; the Format
  Background test allows the pane's title to appear twice.
- Progress docs rebuilt from the landing branch's versions with land-r6's rows applied on top,
  so the union merge no longer drops the pen-pressure, ui.pointer and ui.key rows.
