Mostly, I'm interested in the SHA of the commit that was reverted. Getting that into the commit message will identify what content set we're pulling back from history.

This pull request is superseded by #45 , which also restores the Puppet 5.5 docs.

I'm going to close this out now that PR #45 has landed. That restored the Puppet 5.5 docset in commit 9a92320 and moved it to docs/_ovenvox_8x in commit 3cad11c.
