garbage collection following a "git remote rm"?

  i've never checked before, but i assume that if i add a remote, then
fetch from it and subsequently remove that remote, all of the
now-unreferenced remote tracking branches in the object store will
eventually be discarded by garbage collection, yes?

  is there a command (git fsck?) that would display exclusively
objects in the object store corresponding to objects that are suddenly
unreferenced due to the removal of a remote? i was just curious as it
would be neat to demo that in a class.
