Hi Elijah,

Thank you for working on this!

FWIW this report (and your patch series) made me wistful about that Google
Summer of Code project that I hoped would bring about the trick to combine
`--whitespace=fix` with interactive rebases. But in that GSoC project,
this goal was treated as a "bonus feature" and pushed so far back that we
did not even get to analyzing the complexity of the task, let alone any
details.

So I sat down and started that analysis. The result is
https://github.com/gitgitgadget/git/issues/1472 where you can see that
addressing the incompatibility is definitely outside of trivial. It does
seem doable, if Outreachy/GSoC project-sized.

Ciao,
Johannes
