Suggested command in git-filter-branch(1)

+* Remove the original refs backed up by git-filter-branch: say `git
+  for-each-ref \--format="%(refname)" refs/original/ | xargs -n 1 git
+  update-ref -d`.

This is sick.  I would normally just tell people to use 'rm
-rf .git/refs/original', if for some bizarre reason gc has packed
the .refs/original refs then I might do something like the above or
edit .git/packed-refs

How about 'git update-ref -dr refs/original' (and making that work) ?
