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.

fsck gives you dangling ones (and can be told to give you unreachable ones, too) but the list will be more like "these are unreachable, period". It won't be like "these are the ones that recently became unreacable, and I am not listing ones that were unreachable already in N hours ago".
