You want to generalize fast-forward merge, or what's equivalent make fast-formard merge to be special case of head reduction. This should be written both in commit message and in documentation. Do I understand your goal correctly? With head reduction comes three things: * the merge strategy used * recorded parents * generated merge commit message The simplest way would be to use reduced head for all three things, I think. But I also think that this commit in series is the most controversial one; is it realy needed for other commits?

Is it a correct solution, to use provided (specified) heads for generation of merge commit message, but use reduced heads for selecting merge strategy _and_ also as parents recorded in merge commits? Perhaps it is; but IMHO you should have written it in the commit message, and defend this decision in commit message. > + > +The following shows master and three topic branches. topicB is based > +on topicA, topicA is previously branched off from master, and topicC > +is based on the tip of the master branch: > + > +------------ > + o---o---o topicB > + / > + o---o---o topicA > + / > + o---o---o---o---o---o master > + \ > + o---o topicC > +------------ I think I would start with simpler example without 'topicC', of reduction of octopus to two-parent ordinary merge. > diff --git a/git-merge.sh b/git-merge.sh > index 7c34b6c..7c70c56 100755 > --- a/git-merge.sh > +++ b/git-merge.sh > @@ -337,11 +337,16 @@ set x $remoteheads ; shift > > find_reduced_parents "$@" > > -actual_parents=$(git rev-parse "$@") This was introduced by some of your earlier commits, isn't it?
