/* We are using the following method for these scenarios
* 1. Some commands compute a new commit sha, which is dependent on time and therefore
* won't match what is in the control repo. For those commands, we just ensure that
* the errors match what we expect, but we skip comparing the output
* 2. Using the sparse-checkout feature git will error out before checking the untracked files
* so the control repo will show the untracked files as being overwritten while the GVFS
* repo which is using the sparse-checkout will not.
* 3. GVFS is returning not found for files that are outside the sparse-checkout and there
* are cases when git will delete these files during a merge outputting that it removed them
* which the GVFS repo did not have to remove so the message is missing that output.
