"emacs -Q -nw", I guess? We are talking about TTY display, right?

Will this do:
M-: ssssssssssssssssssssssssssssssssssssssssssssssssssss
(keep typing 's' until you get past the right edge of the window, and
the minibuffer resizes to be 2 screen lines instead of just one)?

With C-n? or with something else?

Bottom-left corner or bottom-right corner? If bottom-right, then this
'\' is the continuation glyph, telling you that the line is continued
on the next screen line.

With C-p?
Also, I cannot scroll up two lines unless I first make the mini-window
at least lines high.

I don't see this here, but maybe that's because my terminal isn't
kitty. It does behave like xterm, though.

Here, it never goes away.

Unfortunately, not really.
Thanks.
