[PATCH v2 0/4] Deprecate "not allow as-is commit with i-t-a entries"

 - git-add.txt changes are removed. In the end all kinds of commit
   behave the same way, not worth putting more explanation during the
   transition.

 - reword config text and warning text (or more precisely copy/paste
   from Junio/Jonathan's words)

 - Hard coded release numbers are removed. Now it's simply "in future".

 - Step 2 may be too annoying. Users are warned on every commit if
   commit.ignoreIntentToAdd is set. I think it's good because it keeps
   config file clean, but people may think otherwise.

Nguyễn Thái Ngọc Duy (4):
  cache-tree: update API to take abitrary flags
  commit: introduce a config key to allow as-is commit with i-t-a entries
  commit: turn commit.ignoreIntentToAdd to true by default
  commit: remove commit.ignoreIntentToAdd, assume it's always true
