Hello,
I have a patch for emacs-ess that upgrades the version to 18.10.2.
I switched the download mechanism to git-fetch since there was a
warning about using Github's automatically generated release files.
Additionally, there are a couple fixes applied to the Makefiles and
one of the tests.
Thanks,
Tim
