I think I tend to include the break in all cases, except when I want
an explicit fall through, at which point I'd usually put a comment in
its place to tell people that I really meant it.

If on the hand there's a 'return' involved, I leave out the break
since it's dead anyway.

But I suspect I fail to follow even my own rules sometimes.
