If setup_git_directory() and friends have not been called,
get_git_dir() (because of includeIf.gitdir:XXX) would lead to
die("BUG: setup_git_env called without repository");
There are two cases when a config file could be read before $GIT_DIR
is located.
The first one is check_repository_format(), where we read just the one
file $GIT_DIR/config to check if we could understand this
repository. This case should be safe. We do not parse include
directives, which can only be triggered from git_config_with_options,
but setup code uses a lower-level function. The concerned variables
should never be hidden away behind includes anyway.
The second one is triggered in check_pager_config() when we're about
to run an external git command. We might be able to find $GIT_DIR in
this case, which is exactly what read_early_config() does (and also is
what check_pager_config() uses). Conditional includes and
get_git_dir() could be triggered by the first
git_config_with_options() call there, before discover_git_directory()
is used as a fallback $GIT_DIR detection.
Detect this special "early reading" case, pass down the $GIT_DIR,
either from previous setup or detected by discover_git_directory(),
and make conditional include use it.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
