Git's diff machinery allows users to override the colors to use in
diffs, even the plain-colored context lines. As of 8dbf3eb685 (diff.h:
rename DIFF_PLAIN color slot to DIFF_CONTEXT, 2015-05-27), the preferred
name of the config setting is `color.diff.context`, although Git still
allows `color.diff.plain`.
In the context of `git add -p`, this logic is a bit hard to replicate:
`git_diff_basic_config()` reads all config values sequentially and if it
sees _any_ `color.diff.context` or `color.diff.plain`, it accepts the
new color. The Perl version of `git add -p` needs to go through `git
config --get-color`, though, which allows only one key to be specified.
The same goes for the built-in version of `git add -p`, which has to go
through `repo_config_get_value()`.
The best we can do here is to look for `.context` and if none is found,
fall back to looking for `.plain`, and if still not found, fall back to
the hard-coded default (which in this case is simply the empty string,
as context lines are typically rendered without colored).
This still leads to inconsistencies when both config names are used: the
initial diff will be colored by the diff machinery. Once edited by a
user, a hunk has to be re-colored by `git add -p`, though, which would
then use the other setting to color the context lines.
In practice, this is not _all_ that bad. The `git config` manual says
this in the `color.diff.<slot>`:
`context` (context text - `plain` is a historical synonym)
We should therefore assume that users use either one or the other, but
not both names. Besides, it is relatively uncommon to look at a hunk
after editing it because it is immediately staged by default.

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-<commandname>.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://lore.kernel.org/git/, http://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
