[PATCH v4 0/4] git add --chmod: always change the file

[Thomas Gummerer <t.gummerer@gmail.com>]

Thanks Junio for the review of my last round.

Changes since then:
[1/4]: patch unchanged
[2/4]: Only adds a test now, and corrects the type of the argument of
       chmod_path, but leaves the rest of the patch unchanged.
[3/4]: chmod_index_entry now takes a char as argument which can either
       be + or -, and changes the mode based on that, instead of using
       the 0777 or 0666 mode that was passed in from the outside.
[4/4]: Adapted to the different behaviour of chmod_index_entry and
       added tests as suggested by Junio.

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