A left-drag of the fill handle filled at once and offered no choice. A button now appears below the filled range; its menu undoes that fill and reruns edit.autoFill in the chosen mode. It goes away when the workbook changes or the selection moves.
A Ctrl+click went to the add-to-selection branch, so the link under the pointer was never followed. It now goes through follow_link like a plain click (asks before opening web addresses, jumps to references).
