Thanks for all of the replies.
Zhenya, history-next/prev was the key. Excellent! Now I can work happily. Thanks very much.
I noticed that caml-list emails have reply-to set to the person who posted. Is it the convention to reply off-list for most followups of this kind?
(Francois, I checked and ^P and ^N actually are the Emacs previous/next line keys in my vanilla Emacs—it wasn’t just my fingers that thought so! Meta-P and Meta-N are unbound. (I have to use the uber-traditional Esc- prefix to get Meta, as Alt- and Apple- do other things by default for me.))
(Tao: Yeah, lately Apple sometimes seems to have a “if it’s not broken and is better than anything else, let’s mess it up” attitude. I think the X is supposed to be Roman numeral 10, so maybe Apple is planning to increment X and doesn’t like "OSXI".)

I agree with your reading of lambda-term-inputrc man page, but I disagree with your reading of the output of lambda-term-actions. I think the following stanza should give you the effect you want:
[read-line]
C-p: history-next
C-n: history-prev

Best,
