Log:
  sh: Do not enter consecutive duplicates into the history.
  
  This simply sets a flag in libedit. It has a shortcoming in that it does not
  apply to multi-line commands.
  
  Note that a configuration option for this is not going to happen, but always
  having this seems better than not having it. NetBSD has done the same.
