Let's push the world a bit towards "perfect" state ;)

- zip.vim and tar.vim (omitted in the CVE description) only seem to be
shipped with vim as of vim 7.0.  6.x versions of vim do not have them
and can not be used to browse .zip/.tar archives.  Affected in versions
used in 7.0 and 7.1.  I don't see them in 6.4 tarball, so no sure why
advisory states 6.4 is not affected.  6.3 and 6.0 were verified to be
unaffected.

- netrw seems to be used as directory explorer as of vim 7.0.  However,
netrw test case triggers similar problem in explorer.vim plugin used in
vim 6.x versions.  So netrw test reports vulnerable for multiple
versions back to 6.0 (tested on 7.1, 7.0, 6.3 and 6.0), even though
different plugins are affected on 7.x and 6.x.

- All other tests affect vim versions at least back to 6.0 (tested on
versions listed above).
