From 84054f79de35015fc92f73ec4780102dd820e452 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 9 Jun 2011 16:56:19 -0400 Subject: [PATCH] clone: accept config options on the command line Clone does all of init, "remote add", fetch, and checkout without giving the user a chance to intervene and set any configuration. This patch allows you to set config options in the newly created repository after the clone, but before we do any other operations. In many cases, this is a minor convenience over something like: git clone git://... git config core.whatever true But in some cases, it can bring extra efficiency by changing how the fetch or checkout work. For example, setting line-ending config before the checkout avoids having to re-checkout all of the contents with the correct line endings. It also provides a mechanism for passing information to remote helpers during a clone; the helpers may read the git config to influence how they operate.
