From 7ab891898524abbeb2c52f3f55fcf5e2457f930b Mon Sep 17 00:00:00 2001 From: Jacob Abel Date: Wed, 17 May 2023 21:48:47 +0000 Subject: worktree add: add --orphan flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for creating an orphan branch when adding a new worktree. The functionality of this flag is equivalent to git switch's --orphan option.
