! 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.
