[PATCH v3 0/4] git add --chmod: always change the file

Thanks to Junio on setting me straight on the change of behaviour in the previous round.

This round includes a similar change, which does however not change the behaviour of update-index with repeated arguments. I still think the unification of the way git add and git update-index handle chmod is useful, when we can keep the behaviour with multiple arguments in update-index the same.

Thomas Gummerer (4):
  add: document the chmod option
  update-index: use the same structure for chmod as add
  read-cache: introduce chmod_index_entry
  add: modify already added files when --chmod is given
