It's at git://iabervon.org/~barkalow/git/ builtin-rebase-int

I was mainly working from rebase--interactive, and a lot of what I have is
the code for the particular steps that uses.

Not at the moment. I've been busy with a new job recently, and my git work
has mainly been on builtin-clone.

I haven't actually looked at it recently, so I don't entirely remember how
far I got. I think my most recent code is based around the idea of having
a sequence file and a file of saved options, but it's just kind of a
sketch and most of the stuff isn't actually implemented. IIRC, the last
thing I ran into was trying to decide where to leave the line for the step
in progress. I think I'd settled on a set of operations that a step should
define:
a) try doing the step, which either works and you go to (c), or it
requires user assistance and you exit now and later start at (b)
b) apply the stuff the user did to help
c) finish up anything common
For example, merging would be:
a) try an automatic merge; if it works, succeed, otherwise, write out
conflict files and exit
b) check that the index is merged
c) make a merge commit
IIRC, for some operations (b) was more interesting, because the case that
didn't have user assistence generates the final state differently and
there's less in (c).
