This seems like an obscure way to write $'\n'  :)   (my second suggestion)

That's true, but I think you might not have gotten the point of the
snippet.  The point is that you can use $i after the while loop, but
without the subshell you can't.  The subshell is part of the pipeline.

That might not be convenient for all scripts, but it's sufficient for many
(especially in the absense of lastpipe).
