Re: [PATCH] rebase -i: remember merge options beyond continue actions

> From: Fabian Ruch <bafain@gmail.com>

> If the user specifies a merge strategy or strategy options in

> In the implementation, the "do_merge" guard to check for a given
> merge strategy or strategy options is implied by passing these
