chainlint.sed swallows top-level here-docs to avoid being fooled by content which might look like start-of-subshell. It likewise swallows here-docs in subshells to avoid marking content lines as breaking the &&-chain, and to avoid being fooled by content which might look like end-of-subshell, start-of-nested-subshell, or other specially-recognized constructs. At the time of implementation, it was believed that it was not possible to support arbitrary here-doc tag names since 'sed' provides no way to stash the opening tag name in a variable for later comparison against a line signaling end-of-here-doc. Consequently, tag names are hard-coded, with "EOF" being the only tag recognized at the top-level, and only "EOF", "EOT", and "INPUT_END" being recognized within subshells. Also, special care was taken to avoid being confused by here-docs nested within other here-docs. In practice, this limited number of hard-coded tag names has been "good enough" for the 13000+ existing Git test, despite many of those tests using tags other than the recognized ones, since the bodies of those here-docs do not contain content which would fool the linter. Nevertheless, the situation is not ideal since someone writing new tests, and choosing a name not in the "blessed" set could potentially trigger a false-positive. To address this shortcoming, upgrade chainlint.sed to handle arbitrary here-doc tag names, both at the top-level and within subshells.

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.
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
