I addressed Jonathan's concern, though.

Is there any reason why you avoid using `git rebase -ir` here? This should
be so much easier via

	git checkout pk/rebase-i-in-c-6-final
	git rebase -ir js/rebase-in-c-5.5-work-with-rebase-i-in-c^

and then inserting this at the appropriate position, followed by the `git
range-diff @{-1}...`:

	git am -s mbox
	git update-ref js/rebase-in-c-5.5-work-with-rebase-i-in-c HEAD

Ciao,
