clang-format: adjust line break penalties We really, really, really want to limit the columns to 80 per line: One of the few consistent style comments on the Git mailing list is that the lines should not have more than 80 columns/line (even if 79 columns/line would make more sense, given that the code is frequently viewed as diff, and diffs adding an extra character). The penalty of 5 for excess characters is way too low to guarantee that, though, as pointed out by Brandon Williams. From the existing clang-format examples and documentation, it appears that 100 is a penalty deemed appropriate for Stuff You Really Don't Want, so let's assign that as the penalty for "excess characters", i.e. overly long lines. While at it, adjust the penalties further: we are actually not that keen on preventing new line breaks within comments or string literals, so the penalty of 100 seems awfully high. Likewise, we are not all that adamant about keeping line breaks away from assignment operators (a lot of Git's code breaks immediately after the `=` character just to keep that 80 columns/line limit). We do frown a little bit more about functions' return types being on their own line than the penalty 0 would suggest, so this was adjusted, too. Finally, we do not particularly fancy breaking before the first parameter in a call, but if it keeps the line shorter than 80 columns/line, that's what we do, so lower the penalty for breaking before a call's first parameter, but not quite as much as introducing new line breaks to comments.

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):
