On a linux machine, with Matlab 2016a:

It lacks the ability to position the cursor.
If that is not the actual type of terminal you have,
use the Bourne shell command `TERM=... export TERM' (C-shell:
`setenv TERM ...') to specify the correct type.  It may be necessary
to do `unset TERMINFO' (C-shell: `unsetenv TERMINFO') as well.

The terminal then becomes unusable (e.g. can't "C-x C-c") then I have kill

As for the pager, I don't know how to determine if it is a separate process
since my ML session is run on a separate node from the one I launch it from
(i.e. "ps -u $USER" in the launching terminal won't even list Matlab). All I
can tell is that the pager is pretty basic: "space" scrolls one page
forward, any other key scrolls one line forward, "q" quits the pager. Looks
like its no more than "more", much less capable than "less".

OK, thanks.

We might be able to come up with some tests but I don't think it really matters. The point is that Matlab users who begin using Octave won't expect to be able to run something like Emacs in the command window.

Having the capabilities of less would be nice, but I don't see it as necessary. We could also just provide good ways to search in the command window without having output paged and that would probably satisfy most users. We've already disabled the pager by default anyway because having it enabled seems to confuse new users. So I don't think most GUI users will miss it much even if we provide nothing but scrollbars.
