What I meant is that we should simply tell people to always put it at
the end.  AFAIK you can always put it at the end, so it's a simpler
rule to follow.  That doesn't mean we have to reject a `-` in other
positions (so we can also accept the usual other rule, but we don't
need to advertise it as much as the main rule).
