I attach an improved patch1886.use.tarfile.module.diff that fixes all
bugs addressed in this issue.

It also removes second call to compression program leaving that
privilege to tar.

This bug is illustrated and patched (not released yet as somebody needs
to reopen it) in issue 1885. The extra path component is taken from the
name passed to GzipFile.
