unstr always fails with "data file corrupted"

[Gunter Ohrner]

The "unstr" program shipped with fortune-mod does not work at all:

$ cat > test.fort
Fortune1
%
Fortune2
%
Fortune3^D^D

$ strfile test.fort
"test.fort.dat" created
There were 3 strings
Longest string: 9 bytes
Shortest string: 8 bytes

$ unstr test.fort.dat
Input file: test.fort.dat
unstr: data file corrupted

$ fortune test.fort
Fortune1

$ fortune test.fort
Fortune3

$
