    I'd suppose that the terminal has one idea of the cursor location, and
    undo happens at other points.

Maybe so, but to really understand, I need a test case.

    However, since the whole point of term is to provide an
    ncurses-capable terminal, and since undo or any other output or cursor
    movement operation not initiated from the device writing into the
    pseudotty would lead to a discrepancy between the screen contents and
    the application's expectations, _any_ editing by the user including
    undo would seem completely pointless.

Not in line mode, though.
