Git commit --fixup, but automatic

 git-absorb is a port of hg absorb to Git.
 .
 git absorb automatically identifies which commits are safe to modify,
 and which indexed changes belong to each of those commits. It then writes
 fixup! commits for each of those changes. These fixups can later be folded
 into the feature branch with Git's built-in autosquash functionality.
 .
 This package contains the following binaries built from the Rust crate
