histedit: handle multiple spaces between action and hash (issue3893)

There is some clue that the previous code intended to handle that but it was
actually not the case.

As a result action could apply to the empty string '' changeset,
leading to the use the current working directory parent in some
operations.

Test argument handling and various data parsing

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 2

Test short version of command
---------------------------------------

Note: we use varying amounts of white space between command name and changeset
short hash. This tests issue3893.
