What does the extra -- do?

In cases where there is a branch named foo and also a file named foo, it disambiguates that I'm talking about the branch, not the file. If you wanted to name the file, you'd put the -- before src_branch rather than after. This actually came up because deploy is a branch and also a directory that exists in the content of branch main right now.
