Subject: [PATCH 2/2] git clone: don't clone into non-empty directory
Date: Wed, 1 Jul 2020 11:36:53 +0200 [thread overview]
Message-ID: <20200701093653.3706-3-ben@wijen.net> (raw)
In-Reply-To: <20200701093653.3706-1-ben@wijen.net>
When using git clone with --separate-git-dir realgitdir and
realgitdir already exists, it's content is destroyed.
Make sure we don't clone into an existing non-empty directory.
