Yeah, good point. You can still use a shell script as restore_command,
pass the %r option to it, and do the deletion there.

I didn't intend to replace pg_standby when I started this, it just kind
of happened. Maybe we should provide a sample script similar to
pg_standby, to be used instead of plain 'cp', that does the cleanup too.
