1. Merge this Pull Request instead of the original, or

2. Ask your contributor to locally incorporate these commits and push them to the original Pull Request

   Incorporate changes via command line

   git fetch https://github.com/iterative/shtab pull/101/head
   git merge --ff-only FETCH_HEAD

NOTE: As code is pushed to the original Pull Request, Sourcery will re-run and update (force-push) this Pull Request with new refactorings as necessary. If Sourcery finds no refactorings at any point, this Pull Request will be closed automatically.
