In GNU tar (i.e. gtar), the --exclude option with a glob only matches the subdirectories, but not the directory itself. For example, --exclude test-tar/a/b/* would exclude anything inside of b, but not b itself. However, bsdtar is excluding the directory itself as well. My question is how do I make bsdtar act the same as GNU in this regard?

Here is an example script the demonstrates the problem:

#!/usr/bin/env bash

echo -e "nGiven an archive that looks like this:"
bsdtar -tf test.tgz

echo -e "nExtract the archive excluding test-tar/a/b/* using gtar"
rm -rf test-tar
gtar -xzf test.tgz --exclude 'test-tar/a/b/*'
file test-tar/a/b
file test-tar/a/b/B.txt

echo -e "nExtract the archive excluding test-tar/a/b/* using bsdtar"
rm -rf test-tar
bsdtar -xzf test.tgz --exclude 'test-tar/a/b/*'
file test-tar/a/b
file test-tar/a/b/B.txt

This outputs:

Given an archive that looks like this:
test-tar/
test-tar/a/
test-tar/a/A.txt
test-tar/a/b/
test-tar/a/b/B.txt

Extract the archive excluding test-tar/a/b/* using gtar
test-tar/a/b: directory
test-tar/a/b/B.txt: cannot open `test-tar/a/b/B.txt' (No such file or directory)

Extract the archive excluding test-tar/a/b/* using bsdtar
test-tar/a/b: cannot open `test-tar/a/b' (No such file or directory)
test-tar/a/b/B.txt: cannot open `test-tar/a/b/B.txt' (No such file or directory)

My versions are tar (GNU tar) 1.29 and bsdtar 3.3.2.
