[PATCH 3/4] commit: turn commit.ignoreIntentToAdd to true by default

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

From now on, those who has not set commit.ignoreIntentToAdd can commit
as-is even if there are intent-to-add entries. Users are advised/annoyed
to switch to new behavior.

Support for "commit.ignoreIntentToAdd = true" will be dropped in future.
The placeholder "FIXME" needs to be replaced when it's decided what
release will drop config support.
