RE: [PATCH 5/9] pull: ensure --rebase overrides ability to ff

> From: Elijah Newren <newren@gmail.com>

> Now that the handling of fast-forward-only in combination with rebases

> special fast-forward case left within the rebase logic.  Actually, more
> than unnecessary, it's actually a violation of the rules.  As per
> https://lore.kernel.org/git/xmqqwnpqot4m.fsf@gitster.g/, --rebase is
> supposed to override all ff flags other than an explicit --ff-only.
> Ensure that it does so by removing the fast-forward special case that
> exists within the rebase logic.
