Jeff King 9acc591111 config: add a notion of "scope" 
A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.

Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).

This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).

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 http://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 http://news.gmane.org/gmane.comp.version-control.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
