Part of Andre's problem was that this diff wasn't stable because the underlying file format is said to be json so items can move around without issue (e.g. key value pairs swapping position) and that they aren't really working on the json file (it may as well be binary..) but on the jupytper notebook display view, so one step removed from the 'diff'.

Useful suggestion. Maybe need a corresponding `stash --update --keep-index` command 
(https://git-scm.com/docs/git-stash#Documentation/git-stash.txt-Testingpartialcommits)

I see it as a two part problem - diff isn't an appropriate tool (the files are binary-like) but also that it's a review not a resolution of the issues, which has to pick apart, and comment on, the proposed changes.

I also suspect that it's part of the small commit - large commit disparity (patches to be as small as possible but no smaller, so most patches end up too big..)

I think they have a need for a `git stash` that works when there is an intervening commit of the staged files (i.e. clean wrt the stash's staged files).
