This is the 'easiest' thing I could find to make it work (see
attachment) or this branch:
  lp:///~jameinel/bzr/2.2-create-ghost

Basically, it involves manually hacking on Inventory to set a
last-modified revision to a ghost revision, and then inserting the
appropriate text into the repository.

get_parent_map() should then return a ghost parent, and content, etc
should consider itself to be part of that ghost revision.
