In the normal case, Git commands perform repository autodiscovery based on the current working directory. However, in some cases, it's possible to specify a Git working tree unrelated to the current working directory by using GIT_WORK_TREE. In such a case, we want to make sure that we change into the working tree such that our working directory is always within the working tree, if one exists. This is what Git does, and it means that when we write files into the repository, such as a .gitattributes file, we write them into the proper place. Note also that we adjust the code to require that the working directory be non-empty when we require a working copy instead of that the repository be non-bare. That's because we don't want people to be working inside of the Git directory in such situations, where the repository would be non-bare but would not have a working tree. We add tests for this case for track and untrack, which require a working tree, and for checkout, which requires only a repository. This means that we can verify the behavior of the functions we've added without needing to add tests for this case to each of the subcommands.
