Hi @stephens2424!

Thanks for merging the fixes from our earlier pull request. They were generated by CodeLingo which we've used to find a further 94 issues in the repo. This PR adds a set of CodeLingo Tenets which catch any new cases of the found issues in PRs to your repo.

CodeLingo will also send follow-up PRs to fix the existing repos in the codebase. Install CodeLingo GitHub app after merging this PR. It will always be free for open source.

We're most interested to see if we can help with project specific bugs. Tell us about more interesting issues and we'll see if our tech can help - free of charge.

Thanks, Leila and the CodeLingo Team
