Find issues to resolve for this lesson

[weaverbel]

This lesson has now been migrated to the Library Carpentry organisation. All updates and new issues should happen on THIS repo.

All the issues that need resolving are still at the old location, however: https://github.com/data-lessons/library-git-DEPRECATED/issues

Find issues to resolve there and fix them here.
