bug#2350: 23.0.90; compilation-mode inserts output in the wrong location

But what isn't clear is whether it's always the right thing to do: it's
clear in this particular use of narrow, but there might be other uses of
narrow in conjunction with compilation buffers where it would be the
wrong thing to do.
