We could add a fallback to get the terminal size directly if readline
is disabled, but IMHO we should also definitely add support for
overriding the terminal size with COLUMNS and LINES regardless.

I don't know, that's a question for the Emacs devs who work on the
Octave mode. You might have better luck asking on an emacs list. I
suspect it's because Emacs wants to be in charge of line editing,
history, completion, etc, and maybe there is some interference or
other reason to want to disable readline in the target program.

We talked about all of this a while ago on Debian #675509 [1] where
you proposed that Octave mode should not be based on comint mode. I
have no opinion or insight into what any of that means, but it is
still based on comint mode today and does still set the
--no-line-editing option. IMHO taking this up with the maintainers of
the Octave mode script is the best way forward.
