Huh, wait. There's no -a option in pg_standby, so I presume you're
planning to add that too. I don't like confusing pg_standby into this,
the docs are currently quite clear that if you want to use the built-in
standby mode, you can't use pg_standby, and this would muddy the waters.

Maybe we could add a new pg_cleanuparchive binary, but we'll need some
discussion...
