diff: skip implicit no-index check when given --no-index We can invoke no-index mode in two ways: by an explicit request from the user, or implicitly by noticing that we have two paths, and at least one is outside the repository. If the user already told us --no-index, there is no need for us to do the implicit test at all. However, we currently do, and downgrade our "explicit" to DIFF_NO_INDEX_IMPLICIT. This doesn't have any user-visible behavior, though it's not immediately obvious why. We only trigger the implicit check when we have exactly two non-option arguments. And the only code that cares about implicit versus explicit is an error message that we show when we _don't_ have two non-option arguments. However, it's worth fixing anyway. Besides being slightly more efficient, it makes the code easier to follow, which will help when we modify it in future patches.

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 http://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-commandname.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 http://news.gmane.org/gmane.comp.version-control.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):
