The expected behaviour for `git config list` is:
A. Without `--global`, it should not bail on unreadable/non-existent
global config files.
B. With `--global`, it should bail when both `$HOME/.gitconfig` and
`$XDG_CONFIG_HOME/git/config` are unreadable. It should not bail
when one or more of them is readable.
The previous patch, config: read global scope via config_sequence,
introduced a regression in scenario B. When both global config files are
unreadable, running `git config list --global` would not fail. For
example, `GIT_CONFIG_GLOBAL=does-not-exist git config list --global`
exits with status code 0.
Assuming that `config_source->scope == CONFIG_SCOPE_GLOBAL` iff the
`--global` argument is specified, use this to determine whether to bail.
When reading only the global scope and both config files are unreadable,
then adjust the return code to be non-zero.
Note: When bailing, the exit code is not determined by sum of the return
codes of the underlying operations. Instead, the exit code is modified
via a single decrement. If this is undesirable, we can change it to sum
the return codes of the underlying operations instead.
Lastly, modify the tests to remove the known breakage/regression. The
tests for scenario B will now pass.

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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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 and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
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
