Documentation/config/rebase.txt

rebase.useBuiltin::
	Set to `false` to use the legacy shellscript implementation of
	linkgit:git-rebase[1]. Is `true` by default, which means use
	the built-in rewrite of it in C.
+
The C rewrite is first included with Git version 2.20. This option
serves an an escape hatch to re-enable the legacy version in case any
bugs are found in the rewrite. This option and the shellscript version
of linkgit:git-rebase[1] will be removed in some future release.
+
If you find some reason to set this option to `false` other than
one-off testing you should report the behavior difference as a bug in
git.

rebase.stat::
	Whether to show a diffstat of what changed upstream since the last
	rebase. False by default.

rebase.autoSquash::
	If set to true enable `--autosquash` option by default.

rebase.autoStash::
	When set to true, automatically create a temporary stash entry
	before the operation begins, and apply it after the operation
	ends.  This means that you can run rebase on a dirty worktree.
	However, use with care: the final stash application after a
	successful rebase might result in non-trivial conflicts.
	This option can be overridden by the `--no-autostash` and
	`--autostash` options of linkgit:git-rebase[1].
	Defaults to false.

rebase.missingCommitsCheck::
	If set to "warn", git rebase -i will print a warning if some
	commits are removed (e.g. a line was deleted), however the
	rebase will still proceed. If set to "error", it will print
	the previous warning and stop the rebase, 'git rebase
	--edit-todo' can then be used to correct the error. If set to
	"ignore", no checking is done.
	To drop a commit without warning or error, use the `drop`
	command in the todo list.
	Defaults to "ignore".

rebase.instructionFormat::
	A format string, as specified in linkgit:git-log[1], to be used for the
	todo list during an interactive rebase.  The format will
	automatically have the long commit hash prepended to the format.

rebase.abbreviateCommands::
	If set to true, `git rebase` will use abbreviated command names in the
	todo list resulting in something like this:
+
-------------------------------------------
	p deadbee The oneline of the commit
	p fa1afe1 The oneline of the next commit
	...
-------------------------------------------
+
instead of:
+
-------------------------------------------
	pick deadbee The oneline of the commit
	pick fa1afe1 The oneline of the next commit
	...
-------------------------------------------
+
Defaults to false.
