The option --ita-invisible-in-index exposes the "ita_invisible_in_index" diff flag to outside to allow easier experimentation with this new mode. The "plan" is to make --ita-invisible-in-index default to keep consistent behavior with 'status' and 'commit', but a bunch other commands like 'apply', 'merge', 'reset'.... need to be taken into consideration as well.
