I think the first of these (copy out the bits you want) is the only one
we should really be recommending to users or intending to support in the
future.  (Of course Alexander is more than a user so I don't mind John
telling, but I wouldn't want people in general changing their index
files.)

Possibly we should add some command to vacuum out unused revisions, but
that should be built up on proper apis.  Perhaps the best way is to do a
plugin to branch a repository, copying everything used by every branch
underneath it.
