Subject: [PATCH 17/18] builtin/checkout: add --recurse-submodules switch
Date: Mon,  6 Mar 2017 12:59:18 -0800	[thread overview]
Message-ID: <20170306205919.9713-18-sbeller@google.com> (raw)
In-Reply-To: <20170306205919.9713-1-sbeller@google.com>

This exposes a flag to recurse into submodules
in builtin/checkout making use of the code implemented
in prior patches.

A new failure mode is introduced in the submodule
update library, as the directory/submodule conflict
is not solved in prior patches.
