merge-recursive: increase marker length with depth of recursion Later patches in this series will modify file collision conflict handling (e.g. from rename/add and rename/rename(2to1) conflicts) so that multiply nested conflict markers can arise even before considering conflicts in the virtual merge base. Including the virtual merge base will provide a way to get triply (or higher) nested conflict markers. This new way to get nested conflict markers will force the need for a more general mechanism to extend the length of conflict markers in order to differentiate between different nestings. Along with this change to conflict marker length handling, we want to make sure that we don't regress handling for other types of conflicts with nested conflict markers. Add a more involved testcase using merge.conflictstyle=diff3, where not only does the virtual merge base contain conflicts, but its virtual merge base does as well (i.e. a case with triply nested conflict markers). While there are multiple reasonable ways to handle nested conflict markers in the virtual merge base for this type of situation, the easiest approach that dovetails well with the new needs for the file collision conflict handling is to require that the length of the conflict markers increase with each subsequent nesting. Subsequent patches which change the rename/add and rename/rename(2to1) conflict handling will modify the extra_marker_size flag appropriately for their new needs.

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):
