git.c: provide setup_auto_pager() The previous patch introduced a way for builtins to declare that they will take responsibility for handling the `pager.foo`-config item. (See the commit message of that patch for why that could be useful.) Provide setup_auto_pager(), which builtins can call in order to handle `pager.<cmd>`, including possibly starting the pager. Make this function don't do anything if a pager has already been started, as indicated by use_pager or pager_in_use(). Whenever this function is called from a builtin, git.c will already have called commit_pager_choice(). Since commit_pager_choice() treats the special value -1 as "punt" or "not yet decided", it is not a problem that we might end up calling commit_pager_choice() once in git.c and once (or more) in the builtin. Make the new function use -1 in the same way and document it as "punt". Don't add any users of setup_auto_pager just yet, one will follow in a later patch.

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):
