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

I'm not sure I understand the meaning of "near" here. Can you define
what "near the edge" means, in this context? Does it mean "close", as
in "less than N columns away", or does it mean "flushed all the way to
the edge", i.e. not even a single column between the last character
and the window edge?

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