[PATCHv6 00/10] Reroll of sb/diff-color-move-more

v6:
* fixed issues hinted at by Andrei, thanks! (range-diff below)
* incorporates the new config option, sent separately previously.

v5: This is a resend of sb/diff-color-move-more https://public-inbox.org/git/20180629001958.85143-1-sbeller@google.com/ that fixes an errornous squashing within the series; the end result is the same. range diff is below. (As the latest cooking email said this series is going to land in next soon, I hope this is not too late of a resend; otherwise just ignore it as the end result is the same)

Thanks, Stefan
