Grep and Find count the rows they found, so a hit opens its +Search and a miss fails

Round 18 made a search that found nothing fail, but grep and find never
counted their rows (only a pane search did), so every Grep read as a miss.
Both count the lines they wrote now; a Find or Grep that finds nothing
fails alike, `find: no match, not found` / `grep: ...`, ENOENT, and opens
no empty +Search.
