That's an oversight of the original commit.  Now, instead of failing
even if there is a restore command, wouldn't it be better to pass down
the restore_command to readOneRecord() so as we can optionally
improve the stability of a single record lookup?  This only applies to
a checkpoint record now, but this routine could be called elsewhere in
the future.  Please see the attached.
