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)? > 4.

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. > 6. Scroll up two lines. With C-p? Also, I cannot scroll up two lines unless I first make the mini-window at least lines high. > 7. The continuation glyph on the line before the last one doesn't > appear. Tested on Linux console, St, Xterm and Kitty. I don't see this here, but maybe that's because my terminal isn't kitty. It does behave like xterm, though. > 8. Scroll down more than two lines. > 9.
