This appears in far fewer locations, but it does seem reasonable to add
it to this list as well.

Yea, there's a number of places which seem to have put a newline break
after the extack pointer.

A quick search shows that there are about 970 or so uses where we don't
put a newline, and around 220 where we do.

I suppose I can make a series that cleans all of those up along with
this patch.
