HG METAEDIT
===============================

Setup the Base Repo
-------------------

We start with a plain base repo::

  $ hg init $TESTTMP/metaedit; cd $TESTTMP/metaedit
  $ mkcommit "ROOT"
  $ hg phase --public "desc(ROOT)"
  $ mkcommit "A"
  $ mkcommit "B"
  $ hg up "desc(A)"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit "C"
  created new head
  $ mkcommit "D"
  $ echo "D'" > D
  $ hg commit --amend -m "D2"
  $ hg up "desc(C)"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit "E"
  created new head
  $ mkcommit "F"

TODO: don't create a new commit in this case, we should take the date of the
old commit (we add a default date with a value to show that metaedit is taking
the current date to generate the hash, this way we still have a stable hash
but highlight the bug)
