I just submitted a very small PR[1] for a CLI issue, and I see that the travis build failed due to formatting. I am using emacs, and it is configured to run gofmt on save. I really have not done much Go programming so I was a bit surprised to learn that gofmt uses tabs instead of spaces. Are there style guidelines or conventions documented anywhere? I want to make sure that I follow whatever conventions are in place.
