I quickly tried
sed -e '/]$/N' -e 's/\n//'
in linux and it did it...
But maybe you must adjust it a bit

(I think N just adds the next line to the buffer and you have to
manually get rid of the special newline in the middle.)

i don't quite see what you're trying to do here.
it's doing what you're asking - but that's a no-op,
because N includes an embedded newline.

you can do: sed -e '/]/N' -e 's/\n//'
if you want to join the lines.

or something like this:
sed ':x
	/]$/{
		N
		s/\n/ /
		t x
	}'

if you want it to work for more than two consecutive
lines.
