the series being formatted (for example `git format-patch
--cover-letter --interdiff=feature/v1 -3 feature/v2`).
+--range-diff=<previous>::
+ As a reviewer aid, insert a range-diff (see linkgit:git-range-diff[1])
+ into the cover letter, or as commentary of the lone patch of a
+ 1-patch series, showing the differences between the previous
+ version of the patch series and the series currently being formatted.
+ `previous` can be a single revision naming the tip of the previous
+ series if it shares a common base with the series being formatted (for
+ example `git format-patch --cover-letter --range-diff=feature/v1 -3
+ feature/v2`), or a revision range if the two versions of the series are
+ disjoint (for example `git format-patch --cover-letter
+ --range-diff=feature/v1~3..feature/v1 -3 feature/v2`).
+
+--creation-factor=<percent>::
+ Used with `--range-diff`, tweak the heuristic which matches up commits
+ between the previous and current series of patches by adjusting the
+ creation/deletion cost fudge factor. See linkgit:git-range-diff[1])
+ for details.
