I am on Windoze, so command line is different.

  $ hg amend -e
  abort: cannot amend public changesets

  $ hg phase -d tip -f

  $ hg amend -e
  transaction abort!
  rollback completed
  abort: no username supplied (see "hg help config")

  $ hg amend -e
  warning: ignoring unknown working parent 5d40a9addebf!
  abort: cannot amend public changesets

Is that it? Posted as http://bz.selenic.com/show_bug.cgi?id=4211

How to bring repository to normal state?
Usually I'd just remove everything and clone anew, but cloning
this one was painful and I don't want to repeat the process.
