is always used. Setting this will emit a warning, to alert any
remaining users that setting this now does nothing.
+rebase.backend::
+ Default backend to use for rebasing. Possible choices are
+ 'am' or 'merge' (note that the merge backend is sometimes also
+ refered to as the interactive backend or the interactive
+ machinery elsewhere in the docs). Also, in the future, if the
+ merge backend gains all remaining capabilities of the am
+ backend, this setting may become unused.
+
rebase.stat::
Whether to show a diffstat of what changed upstream since the last
rebase. False by default.
