Obscure bug (found in 1.13.x, including 1.13.25)

[Dana Lacoste]

We use a package system that we call APM but it's really
just a plain old tar file.  If I try to delete a file in the
tar file called "archive" it deletes a lot more than it should :

# tar tvf filename.apm
-rw-r--r-- williams/users    3 2001-09-28 12:35:44 apm_version
-rw-r--r-- williams/users    5 2001-09-28 12:35:44 compression_method
-rw-r--r-- williams/users    3 2001-09-28 12:35:48 name

# tar f filename.apm --delete archive
# tar tvf filename.apm
-rw-r--r-- williams/users    3 2001-09-28 12:35:44 apm_version
-rw-r--r-- williams/users    5 2001-09-28 12:35:44 compression_method

Any suggestions?  I can't find anything in the documentation that
could explain this, so for now I'm treating it as a bug :)

PS: If there is a gnu-tar mailing list (bug list or announce list) that
    I should be following for things like this can you let me know?

Thanks
