Something like that, but perhaps using end-of-visual-line as well.

Ok, so there's a function for that. Would (eq (point) (save-excursion (end-of-visual-line) (point))) not suffice?

Does that constitute at least three different cases we'd need to handle?

- Not near the window edge
- near the edge and newline
- near the edge and no newline?

I'm not sure I understand the meaning of "near" here.

Sorry for being unclear. Let's replace that word with "at".

I'm not sure what you mean by "losing some of the text".

The rightmost characters in each continued line are removed from
display because you put a newline there.

Do you have an example? Unless there's a misunderstanding, this would seem like a bug to me.
