should complain

  $ hg backout
  abort: please specify a revision to backout
  [255]
  $ hg backout -r 0 0
  abort: please specify just one revision
  [255]

basic operation
(this also tests that editor is invoked if the commit message is not
specified explicitly)

should fail

  $ hg backout 1
  abort: cannot backout change that is not an ancestor

backout of merge should fail

  $ hg backout 4
  abort: cannot backout a merge changeset
  [255]

backout of merge with bad parent should fail

  $ hg backout --parent 0 4
  abort: cb9a9f314b8b is not a parent of b2f3bb92043e
  [255]

backout of non-merge with parent should fail

  $ hg backout --parent 0 3
  abort: cannot use --parent on non-merge changeset
  [255]

backout with valid parent should be ok

  $ hg backout -d '5 0' --parent 2 4 --tool=true
  removing d

--no-commit can't be used with --merge

  $ hg backout --merge --no-commit 2
  abort: cannot specify both --no-commit and --merge
  [255]

Ensure that backout out the same changeset twice performs correctly:

  $ hg backout 2
  removing 3
