[Bug-tar] Directories are listed like files, no trailing slash shown

[Live user]

Either using

tar -tf archive.tar

OR

tar --list -f archive.tar

Doesn't show the trailing slash that corresponds to a dir, making 
impossible to know if the content is a directory or a file without 
having to use verbose output.


Example: get the contents of a tar archive to a text file:

tar --list -f myarchive.tar
dir1
dir1/data.dat

Where it should be

dir1/
dir1/data.dat

So I can filter either directories or files:
Only files: tar -tf archive.tar | grep -v /$ > files.txt
Only directories: tar -tf archive.tar | grep /$ > directories.txt
