3. bsdtar -t should read from standard in if a file name is not specified

4. % bsdtar -t
bsdtar: Error opening archive: Failed to open '/dev/st0'

Note that if you specify -f - (aka stdin) it works as expected.

See http://sources.debian.net/src/libarchive/3.1.2-11/tar/bsdtar.c/#L74 for explanation/reason and where to hack if you want to change the behaviour. (See apple ifdef for reference.)

Feel free to convince upstream about changing the behaviour if you still think it should be done after investigating the above.
