This reverts commit 6be4595edb8e5b616c6e8b9fbc78b0f831fa2a87.
That commit weakened the "always" setting of color config so
that it acted as "auto". This was meant to solve regressions
in v2.14.2 in which setting "color.ui=always" in the on-disk
config broke scripts like add--interactive, because the
plumbing diff commands began to generate color output.
This was due to 136c8c8b8f (color: check color.ui in
git_default_config(), 2017-07-13), which was in turn trying
to fix issues caused by 4c7f1819b3 (make color.ui default to
'auto', 2013-06-10). But in weakening "always", we created
even more problems, as people expect to be able to use "git
-c color.ui=always" to force color (especially because some
commands don't have their own --color flag). We can fix that
by special-casing the command-line "-c", but now things are
getting pretty confusing.
Instead of piling hacks upon hacks, let's start peeling off
the hacks. The first step is dropping the weakening of
"always", which this revert does.
Note that we could actually revert the whole series merged
in by da15b78e52642bd45fd5513ab0000fdf2e58a6f4. Most of that
series consists of preparations to the tests to handle the
weakening of "-c color.ui=always". But it's worth keeping
for a few reasons:
- there are some other preparatory cleanups, like
e433749d86 (test-terminal: set TERM=vt100, 2017-10-03)
- it adds "--color" options more consistently in
0c88bf5050 (provide --color option for all ref-filter
users, 2017-10-03)
- some of the cases dropping "-c" end up being more robust
and realistic tests, as in 01c94e9001 (t7508: use
test_terminal for color output, 2017-10-03)
- the preferred tool for overriding config is "--color",
and we should be modeling that consistently
We can individually revert the few commits necessary to
restore some useful tests (which will be done on top of this
patch).
Note that this isn't a pure revert; we'll keep the test
added in t3701, but mark it as failure for now.

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
