I changed my /win/tty/wintty.c to accomplish just that.
I scrapped the old tty_doprev_message() and replaced it with this:

    int
    tty_doprev_message()
    {
        winid prevmsg_win;
        register struct WinDesc *cw = wins[WIN_MESSAGE];
        int i;

        prevmsg_win = create_nhwindow(NHW_MENU);
        putstr(prevmsg_win, 0, "Message History");
        putstr(prevmsg_win, 0, "");
        i = cw->maxcol;
        do {
            if(cw->data[i] && strcmp(cw->data[i], "") )
                putstr(prevmsg_win, 0, cw->data[i]);
            i = (i + 1) % cw->rows;
        } while (i != cw->maxcol);
        putstr(prevmsg_win, 0, toplines);

        display_nhwindow(prevmsg_win, TRUE);
        destroy_nhwindow(prevmsg_win);
        return;
    }

It works as desired for me (MSDOS), but it is far from rigorously tested, so
I can't guess if it will work for other system configurations.  I don't know
if there are side-effects, but I haven't noticed any peculiar behavior.  In
other words, YMMV.
