I do not use this feature myself, but I would think that it should
respect the same DIR_SHOW_OTHER_DIRECTORIES flag (or a parallel flag)
that we already hook into "--untracked={all,normal}".

IOW, given:

  git init
  mkdir untracked ignored
  >untracked/file
  >ignored/file
  echo ignored >.git/info/exclude

I would expect:

  $ git status --short --ignored --untracked=normal
  ?? untracked/
  !! ignored/

  $ git status --short --ignored --untracked=all
  ?? untracked/file
  !! ignored/file

I do not know if anybody cares about the distinction, but optionally we
could give --ignored its own selector, like:

  $ git status --short --ignored=all --untracked=normal
  ?? untracked/
  !! ignored/file

where obviously it would default to "none" (whereas untracked defaults
to "normal"). But the behavior with Antoine's patch is:

  $ git status --short --ignored --untracked=normal
  ?? untracked/
  !! ignored

  $ git status --short --ignored --untracked=all
  ?? untracked/file
  !! ignored

which seems wrong to me for two reasons:

  1. It does not recurse for ignored but untracked entries. Neither does
     the current code, but I think it should.

  2. It loses the trailing slash from the ignored directory in both
     cases (which is printed by the current code).
