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 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)
