rerere.autoUpdate::
When set to true, `git-rerere` updates the index with the
resulting contents after it cleanly resolves conflicts using
previously recorded resolutions. Defaults to false.
rerere.enabled::
Activate recording of resolved conflicts, so that identical
conflict hunks can be resolved automatically, should they be
encountered again. By default, linkgit:git-rerere[1] is
enabled if there is an `rr-cache` directory under the
`$GIT_DIR`, e.g. if "rerere" was previously used in the
repository.
