I have incorporated your two patches and added short options. Updated
patch attached.

This made me wonder, however. The existing -F and -R options set the
record *separator*. The new options, however, set the record
*terminator*. This is the small distinction that you had discovered.

Should we rename the options and/or add that to the documentation, or is
the new behavior obvious and any new terminology would be too confusing?
