tests: disallow the use of abbreviated options (by default) Git's command-line parsers support uniquely abbreviated options, e.g. `git init --ba` would automatically expand `--ba` to `--bare`. This is a very convenient feature in every day life for Git users, in particular when tab completion is not available. However, it is not a good idea to rely on that in Git's test suite, as something that is a unique abbreviation of a command line option today might no longer be a unique abbreviation tomorrow. For example, if a future contribution added a new mode `git init --babyproofing` and a previously-introduced test case used the fact that `git init --ba` expanded to `git init --bare`, that future contribution would now have to touch seemingly unrelated tests just to keep the test suite from failing. So let's disallow abbreviated options in the test suite by default. Note: for ease of implementation, this patch really only touches the `parse-options` machinery: more and more hand-rolled option parsers are converted to use that internal API, and more and more scripts are converted to built-ins (naturally using the parse-options API, too), so in practice this catches most issues, and is definitely the biggest bang for the buck.

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.
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):
