Re: [PATCH 4/8] rebase: prepare to do generic housekeeping

> On successful completion of a rebase in git-rebase--$backend.sh, the
> $backend script cleans up on its own and exits.  The cleanup routine
> is however, independent of the $backend, and each $backend script
> unnecessarily duplicates this work:
>
>     rm -rf "$state_dir"
>     git gc --auto
>
> Prepare git-rebase.sh for later patches that return control from each
> $backend script back to us, for performing this generic cleanup
> routine.

> Another advantage is that git-rebase.sh can implement a generic
> finish_rebase() to possibly do additional tasks in addition to the
> cleanup.
