67 ## in the history for the first line beginning with what you have typed so

69 ## In fact, you often don't even need to use predict-off, because if the
70 ## line doesn't match something in the history, adding a key performs
71 ## standard completion - though editing in the middle is liable to delete
72 ## the rest of the line.
