+git-clone makes it easy to specify a name other than "origin" via the
+`--origin` option, and, as of Git 2.30.0, via the
+`clone.defaultRemoteName` configuration option.  Running `git annex
+init` in a clone on a system where git-annex sets
+`annex.crippledfilesystem` leads to a crash due to a hard-coded
+"refs/remotes/origin".
