It might be useful for reviewing merge/pull requests. But is there a way to display the diff "interleaved" instead of 2-columns side-by-side? (when executing `GIT_EXTERNAL_DIFF=difft git log -p --ext-diff` for example)
There's a basic single-column 'inline' display available if you do `INLINE=y`, but it's not as mature as the side-by-side display yet.
We are working on a code review tool which supports unified diffs with semantic diffing. If that sounds interesting for you, take a look at https://mergeboard.com
