For the record: my non-publishing public clone of mutable-history is

  http://hg.gerg.ca/mutable-history/

Pull from there at will.

Oh, I'm still running 2.9.2 on hg.gerg.ca, so hidden changesets show
up in hgweb. I've got enough going on right now, so I'm not going to
upgrade that server unless it causes problems.
