--listed-incremental bug

[Neologism]

I've found a bug in tar 1.13.19.  I've also verified it with the 1.13.25
alpha as follows:

[src]$ ./tar --version

[src]$ cat > test
This is a test file.
[src]$ ./tar --create --file=test.tar --listed-incremental=snapshot --verbose 
test
test
[src]$ rm test.tar
[src]$ ./tar --create --file=test.tar --listed-incremental=snapshot --verbose 
test
test
[src]$ ./tar --list --file=test.tar
test

During the second create command, I do not expect the file "test" to be
added to the tar file.
