From 9931f18c2dfff2642dea8e1a153eaaa58d7e3c8a Mon Sep 17 00:00:00 2001 From: Kjetil Orbekk Date: Sun, 21 Feb 2021 11:08:28 -0500 Subject: [PATCH] Add support for bare git repositories with git+file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Local git repositories are normally used directly instead of cloning. This commit checks if a repo is bare and forces a clone.
