Re: `looking-back' strange warning

You can pass (point-min) for the limit if that's what you want.
Making it optional Encourages people to think that looking-at is just
like looking-back, with the same performance characteristic, whereas
making it mandatory encourages people to put a reasonable limit and
hence avoid pathological behavior at the end of large buffers.
