"git tbdiff" that lets us compare individual patches in two iterations of a topic has been rewritten and made into a built-in command. * js/range-diff: (21 commits) range-diff: use dim/bold cues to improve dual color mode range-diff: make --dual-color the default mode range-diff: left-pad patch numbers completion: support `git range-diff` range-diff: populate the man page range-diff --dual-color: skip white-space warnings range-diff: offer to dual-color the diffs diff: add an internal option to dual-color diffs of diffs color: add the meta color GIT_COLOR_REVERSE range-diff: use color for the commit pairs range-diff: add tests range-diff: do not show "function names" in hunk headers range-diff: adjust the output of the commit pairs range-diff: suppress the diff headers range-diff: indent the diffs just like tbdiff range-diff: right-trim commit messages range-diff: also show the diff between patches range-diff: improve the order of the shown commits range-diff: first rudimentary implementation Introduce `range-diff` to compare iterations of a topic branch ...
