[PATCH v3 1/3] rebase: simplify code related to imply_merge()

From: Oswald Buddenhagen <oswald.buddenhagen@gmx.de>
Date: Oct 20, 2023, 09:36 UTC
Message-ID: <20231020093654.922890-2-oswald.buddenhagen@gmx.de>
In-Reply-To: <20231020093654.922890-1-oswald.buddenhagen@gmx.de>

The code's evolution left in some bits surrounding enum rebase_type that don't really make sense any more. In particular, it makes no sense to invoke imply_merge() if the type is already known not to be REBASE_APPLY, and it makes no sense to assign the type after calling imply_merge().

enum rebase_type had more values until commit a74b35081c ("rebase: drop support for `--preserve-merges`") and commit 10cdb9f38a ("rebase: rename the two primary rebase backends"). The latter commit also renamed imply_interactive() to imply_merge().
