Thanks, but I am confused.

The stuff goes through make_absolute_path() so we must be certain that
this has to be a local filesystem entity _if_ it is a repository.

But when will we see a file at repo_name in this new codepath?  In what
situation would get_repo_path(repo_name, &is_bundle) return NULL but the
added file_exists(repo_name) would yield true to bypess your die()?

Hmm, good point. I didn't look carefully enough into get_repo_path. It
is not really about finding a repo, but rather about finding a directory
or filename. Plus, my file_exists() isn't quite right, anyway. We really
want to make sure $repo_name.git, $repo_name.bundle, etc don't exist.
But get_repo_path has already done that for us, so we should just trust
its output.

Yeah, I think that is a better fix.
