From 132f600b060c2db7fd3d450dfadb6779a61c648a Mon Sep 17 00:00:00 2001 From: Emily Shaffer Date: Thu, 20 Feb 2020 19:10:27 -0800 Subject: [PATCH] clone: pass --single-branch during --recurse-submodules Previously, performing "git clone --recurse-submodules --single-branch" resulted in submodules cloning all branches even though the superproject cloned only one branch. Pipe --single-branch through the submodule helper framework to make it to 'clone' later on.
