I think this will become (more) reviewable if it is split into two patches (at least). A preliminary patch that does the style changes and line wrapping (left below) as step #1, and all the rest on top as step #2. > diff --git a/git-rebase--interactive.sh b/git-rebase--interactive.sh > index 331c8dfea..65ff75654 100644 > --- a/git-rebase--interactive.sh > +++ b/git-rebase--interactive.sh > @@ -1,5 +1,7 @@ > -# This shell script fragment is sourced by git-rebase to implement > -# its interactive mode.

That is why it is better to leave these changes to a separate patch after preliminary clean-up.
