I agree that "Let's check for this" is a good idea, but do not necessarily agree with "i.e.". Don't we have a helper that takes the path to an existing directory and answers "Yup, it does look like a Git repository"? Using that is a lot more in line with what you claimed to do in the title for this patch. I haven't read 3/3 yet, but as I said, I suspect it is reasonable to DWIM and use the object store associated with the directory we found to be a repository.
