We got a support email about this, if it was you then you probably already know the solution, but otherwise:
The port 80 listener is just a redirect to https. Add `Disable-HTTP-Redirector=true` to gravwell.conf to disable that redirector. The option is documented in the document you linked, but I can see how you'd miss it: we talk about "HTTP" and "HTTP" rather than "port 80" which would make it more of a pain to search for.
Changing `Web-Port` will change the HTTPS listener port, as you figured out.
We're working on populating our new knowledge base now with the answers to this and other questions which came up during our community edition rollout: http://help.gravwell.io/knowledge/
