Looks OK, but

 - Needs a patch to Documentation/config.txt and possibly also
   Documentation/git-rebase.txt

 - Needs tests somewhere in t34?? series.

Also I think "git rev-list" line has got way too long.  As it is
already using backslash-continuation, do not hesitate to fold it
further, e.g. 

        git rev-list $merges_option --format="%m%H ${format-%s}" \
                --reverse --left-right --topo-order \
                $revisions ${restrict_revision+^$restrict_revision} | \
                sed -n "s/^>//p" |
	while ...

Thanks.
