Using:

(git ls-files; git submodule foreach --recursive "git ls-files | sed 
s_^_\$sm_path/_" | sed /^Entering/d) > files.txt

and:

        subprocess.check_call([tar_cmd,
                               "-cf", tarfile,
                               "-v" if self.debug else "",
                               "-T", "files.txt"], cwd=data_dir,
                              stdin=self._devnull, stdout=self._stdout)

Current /master and submodules generated tarball is ~305MB uncompressed.

Kamil do you mind testing this command on NetBSD?

(obviously 'files.txt' goes in tmpdir).

Phil.
