From be254a0ea99b441a6c514cb8b25cd72357383700 Mon Sep 17 00:00:00 2001 From: Jens Lehmann Date: Thu, 11 Nov 2010 00:55:02 +0100 Subject: [PATCH] Add the 'fetch.recurseSubmodules' config setting This new boolean option can be used to override the default for "git fetch" and "git pull", which is to not recurse into populated submodules and fetch all new commits there too.
