Run a dummy edit to make sure we get tip^^ correctly via revsingle.

--------------------------------------------------------------------

  $ HGEDITOR=cat hg histedit "tip^^"

  pick eb57da33312f 2 three

  pick c8e68270e35a 3 four

  pick 08d98a8350f3 4 five

  # Edit history between eb57da33312f and 08d98a8350f3

  #

  # Commands:

  #  p, pick = use commit

  #  e, edit = use commit, but stop for amending

  #  f, fold = use commit, but fold into previous commit (combines N and N-1)

  #  d, drop = remove commit from history

  #  m, mess = edit message without changing commit content

  $ hg up --quiet

Test that missing revisions are detected

---------------------------------------

  $ HGEDITOR=cat hg histedit "tip^^" --commands - << EOF
