! Check that rewind doesn't delete a file.
! Writing to the file truncates it at the end of the current record. Out
! IO library was defering the actual truncation until the file was rewound.
! A second rewind would then (incorrectly) think the file had just been
! written to, and truncate the file to zero length.
