From: Derrick Stolee <derrickstolee@xxxxxxxxxx> The previous change created the logic for copying a file by name. Now, first inspect the URI for an HTTP(S) prefix and use git-remote-https as the way to download the data at that URI. Otherwise, check to see if file:// is present and modify the prefix accordingly.
