      Built-in git-whatchanged

      Now "git log" is in reusable shape, add "git whatchanged" which
      essentially is a synonym with different default for people whose
      fingers are already trained.

      There is a subtle difference from the shell-script version; the
      first line of each entry is now "commit <object name>", instead
      of "diff-tree <object name> (from <object name>)."  I suspect
      that showing the parent name that way is useful, so this may be
      something we would want to fix (the user can say --pretty=raw to
      get that information but that is a bit ugly).
