The "F" as "next argument is a file containing file names" was in XENIX
release 7 and System III versions.  I don't know if it is still there in
current XENIX variants.  Until this discussion, I assumed that this useful
option was part of the standard (AT&T) tar code rather than being something
added by Microsoft/SCO - obviously I have not tried to use it in the last
couple of years.
