I had to make two minor fixes while migrating my work repos:
1. I forgot to honor '@all'; oops!
While I was about it, I also fixed the "access denied"
message to show what rights were being tried when it
failed.
2. I forgot that URLs can have leading slashes (I myself
only use URLs like gs:reponame.git, where gs is an ssh
stanza that describes the git server in question).
