Actually, I think that trying to optimize this is bound to fail: we want
*Help* to show up "instantly", so we're off by a factor of more
than 100, which seems way out of reach (unless there's really an
algorithmic problem in our code, admittedly).
I think the better way out is to do less work. E.g. bound the total
amount printed (and replace the rest with "..." that can be expanded on
demand).
