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

Thanks to Peff and Junio for your inputs on the best way to solve this problem.

The patch series is made up as follows:

[1/4]: Documentation for the chmod option [2,3/4]: Small refactoring to simplify the final step [4/4]: The actual change that introduces the new behaviour.

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
