Subject: [PATCH 5/8] Introduce 'submodule.recurse' option for worktree manipulators
Date: Fri, 26 May 2017 12:10:14 -0700
Message-ID: <20170526191017.19155-6-sbeller@google.com> (raw)
In-Reply-To: <20170526191017.19155-1-sbeller@google.com>

Any command that understands '--recurse-submodules' can have its
default changed to true, by setting the new 'submodule.recurse'
option.

This patch includes read-tree/checkout/reset for working tree
manipulating commands. Later patches will cover other commands.
