When the WAL file with the same name exists in the archive, pg_xlog
and pg_xlog/restore/ which directory should we recover it from?
I'm not sure that we can always make a right decision about that.

How about just making a restore_command copy the WAL files as the
normal one (e.g., 0000...) instead of a pg_xlog/RECOVERYXLOG?
Though we need to worry about deleting them, we can easily leave
the task to the bgwriter.
