[PATCH 0/4] nd/ita-empty-commit update

This version splits the old 1/3 into two, with better description in 1/4. The index_differs_from() also takes a flag to set/clear this new flag instead of relying on has_ita_entries like the old 2/3.

The name ita-invisible-in-index is not perfect but I could not think of any better. Another name could be diff-cached-ignores-ita, but that's just half of what it does. The other half is diff-files-includes-ita...

Nguyễn Thái Ngọc Duy (4):
  Subject: diff-lib: allow ita entries treated as "not yet exist in index"
  diff: add --ita-[in]visible-in-index
  commit: fix empty commit creation when there's no changes but ita entries
  commit: don't be fooled by ita entries when creating initial commit
