Title: Edge guides don't properly link to the current GitHub tree

WIthout the full commit hash, GitHub responds with a 404 when clicking the edge guides "master branch" link. I would have committed this directly to lifo/docrails, but it does include code-related changes in generator.rb, so I thought it was warranted to put it here first.
