Re: Feature request: --preserve-merges to add "exec git merge ..." instead of "pick ..."

It sounds good!
I was using git version 2.7.4 all the time. I should have checked
before posting here :)
Now trying 2.20.1

>From "git help rebase":

           By default, or when no-rebase-cousins was specified,
commits which do not have <upstream> as direct ancestor will keep
           original branch point, i.e. commits that would be excluded
by gitlink:git-log[1]'s --ancestry-path option will keep their
           original ancestry by default. If the rebase-cousins mode is
turned on, such commits are instead rebased onto <upstream> (or
           <onto>, if specified).

I am not sure if this criterion (which ancestors it has) will always
produce the behavior I am looking for.
I will have to experiment a bit.

Thanks for now, I will post again with new thoughts once I have done
some experiments.
